Israel conducted another devastating airstrike near Beirut airport overnight in an attempt to wipe out Hezbollah's heir apparent after former chief Hassan Nasrallah was killed one week ago.

The Israeli air force launched wave upon wave of punishing strikes in Beirut's southern suburbs overnight into this morning, battering the Dahiyeh area where Hezbollah's underground headquarters are based.

But one enormous cacophony of explosions that shook buildings for miles around suggested Israel had deployed yet more Joint Direct Attack Munitions (JDAMs) - bombs designed to penetrate deep into underground structures.

Unconfirmed Israeli media reports said the IAF had targeted Hashem Safieddine, another hardline cleric and cousin of Nasrallah who many analysts believed was a shoo-in to replace the slain Hezbollah leader.

It is unclear whether Saffieddine was present at the site of the attack. 

The intense bombardment came after the IDF issued yet another evacuation order for communities across southern Lebanon.

Lebanese citizens were told to leave Nabatieh, a provincial capital, and other communities north of the Litani River, which formed the northern edge of the border zone established by the UN Security Council after the 2006 war in a resolution that both sides accuse the other of violating.

Israel also conducted one of its most deadly strikes in the West Bank in decades overnight, with at least 18 people said to have been killed at the Tulkarm refugee camp, Palestinian health authorities claim.

The IDF reported its strike killed Hamas leader Zahi Yaser Abd al-Razeq Oufi, who it accused of participating in numerous attacks.

Hezbollah's Executive Council leader Hashim Safieddine is expected to become the organisation's chief following the death of Nasrallah - but Israel is targeting him with strikes

Hezbollah's Executive Council leader Hashim Safieddine is expected to become the organisation's chief following the death of Nasrallah - but Israel is targeting him with strikes

Israel announced this week that its troops had started 'ground raids' into parts of southern Lebanon, a stronghold of Hezbollah, after days of heavy bombardment of areas across the country where the group holds sway.

At least nine Israeli soldiers have been killed in clashes with militants in the past three days as IDF units comb through villages in southern Lebanon to close off tunnels and eradicate Hezbollah positions. 

Who is Hashem Safieddine?

Hasham Safieddine has been pegged as Hassan Nasrallah's replacement as secretary-general of Hezbollah.

Safieddine currently oversees the group's political affairs and sits on the Jihad Council, managing its military operations.

He was considered Hassan Nasrallah's second in command until his death in an Israeli airstrike on October 27, 2024.

Safieddine is the maternal cousin of Nasrallah and, like him, is a cleric who wears to black turban to denote descent from the Prophet Mohammed.

Safieddine is close to Iran and his son, Rida, is married to Zeinab Soleimani, the daughter of an Iranian general who was famously killed in a U.S. airstrike in Iraq in 2020.

Safieddine was born in Lebanon in 1964 and studied theology with his cousin across the region before returning to Lebanon in 1994, two years after Nasrallah took the top job.

Under Nasrallah, Hezbollah - barely a decade old - would transform from a fledgling Shia fighting force of the Lebanese Civil War and 1982 Israeli Invasion into a political and military powerhouse.

Their leadership was praised by many in Lebanon as Israel withdrew from the south in 2000 and were held to a stalemate in 2006.

They have also come under fire for not respecting the terms of Resolution 1701, demilitarising the border zone, and backing Assad in the Syrian Civil War.

Opinion in Hezbollah remains divided in Lebanon, offering social services in lieu of the ailing government as a 'state within a state' but also acting recklessly and representing only a slither of the diverse population.

Hezbollah meanwhile claims it fought off Israeli troops on the border, set off two explosive devices against advancing soldiers, and ambushed an IDF united close to the village of Adaisseh.

The militant group also said it kept up its rocket fire across the border, with sirens warning of incoming fire blaring in northern Israel early this morning. 

The IDF's ground operation has been supported by near-round-the-clock airstrikes across southern and eastern Lebanon, Syria and in Beirut, which sustained a constant barrage overnight. 

The escalating assaults by Israel come as it weighs retaliation for Iran's wave of ballistic missiles fired at the country on Tuesday, with the United States saying Israel hitting Iranian oil facilities is on the table. 

The US has called for de-escalation and said this week it was also weighing up the options on the table for a response.

And Iran's Foreign Minister Abbas Araghchi arrived in Beirut today where he will discuss with Lebanese officials the ongoing war between Israel and Hezbollah. 

Israel has said it would respond to Iran's attacks, but does not seek all-out-war.

But clashes in Lebanon pressure Iran to come to the aid of its proxy in Hezbollah, with no sign of Israel's 'raids', billed as being a short term operation to oust Hezbollah from strongholds in the south, abating.

The World Health Organisation reported that 28 health workers were killed in the past day in Lebanon, and access to medical care is becoming limited as three dozen health facilities closed in the south and five hospitals were either partly or fully evacuated in Beirut.

The Lebanese health minister said Israeli strikes that hit nine hospitals and 45 healthcare centres violate international law and treaties.

'International laws are clear in protecting these people - I mean, paramedics,' Firas Abiad said. 

'Who gave Israel the right to be the judge and the executioner at the same time?'

Israel's bombing in Lebanon has killed more than 1,000 people, according to the Lebanese health ministry.

Hundreds of thousands more have been forced to flee their homes in a nation already mired in economic and political crisis.

But strikes have come dangerously close to fleeing civilians and knocked out vital infrastructure in a country already reeling from decades of economic hardship.

An Israeli airstrike cut off a main highway linking Lebanon with Syria, Lebanon's state-run National News Agency said today. 

The airstrike led to the closure of a road near the Masnaa Border Crossing, from where tens of thousands of people fleeing war in Lebanon have crossed into Syria over the past two weeks. 

The Lebanese Red Cross said an Israeli strike also wounded four of its paramedics and killed a Lebanese army soldier as they were evacuating wounded people from the south. 

It said the convoy near the village of Taybeh, which was accompanied by Lebanese troops, was targeted Thursday despite coordinating its movements with UN peacekeepers. 

There was no immediate comment from the Israeli military.

Meanwhile, the Palestinian Health Ministry said 18 people were killed and at least 20 injured late Thursday in an Israeli strike on the Tulkarem refugee camp in the West Bank. 

It was the deadliest strike in the occupied territory since the Israel-Hamas war erupted last October.

The Israeli army said the strike killed Hamas' leader in Tulkarem, adding that the strike was carried out in coordination with the Shin Bet internal security service, but it gave no details on the target. 

Tulkarem is a militant stronghold in the northern West Bank.

Violence has flared across the Israeli-occupied territory since the Israeli-Hamas war erupted last October, particularly in the northern region where Palestinian militant groups have degraded the control of the Palestinian Authority. 

Tulkarem and other northern Palestinian cities have seen some of the worst violence.

An Israeli airstrike on an apartment in central Beirut late Wednesday killed nine people, including seven Hezbollah-affiliated civilian first responders. 

Israel has been pounding areas of the country where the militant group has a strong presence since late September, but has rarely struck in the heart of the capital.

There was no warning before the strike late Wednesday, which hit an apartment not far from the United Nations headquarters, the prime minister's office and parliament.

Residents reported a sulfur-like smell following the strike in Beirut, and Lebanon's state-run National News Agency - without providing evidence - accused Israel of using phosphorous bombs, which can cause severe burns and could violate international law. 

Human rights groups have in the past accused Israel of using white phosphorus incendiary shells on towns and villages in southern Lebanon.

The Israeli army said it has shells containing white phosphorous that do not violate international law, but it did not say if they were used in the attack. 

Army officials said the primary shells they use to create a smokescreen do not contain the substance.

The Israeli military today also told the residents of over 20 more southern towns in Lebanon to evacuate immediately, spokesperson Avichay Adraee said on X.

The Israeli military said Thursday that it had struck around 200 Hezbollah targets across Lebanon, including weapons storage facilities and observation posts. 

It said the strikes killed at least 15 Hezbollah fighters.

What is Resolution 1701? 

UN Resolution 1701 ended the 2006 Lebanon war between Israel and Hezbollah with the agreement that all Israeli forces would withdraw to be replaced by Lebanese and UNIFIL peacekeepers.

Keeping a distance between the two groups, long threatened by the presence of the other, is still considered to be the brightest prospect for long-term stability between Israel and Lebanon.

The Resolution called for the disarmament of all armed groups including Hezbollah in the region, stipulating that only UNIFIL and the Lebanese military could station armed forces south of the Litani River.

Hezbollah and other armed groups in southern Lebanon have not withdrawn, per the agreement. It did agree to disarm south of the river, but not to pull out of southern Lebanon altogether.

It then continued to grow and rearm itself 'exponentially', per Foreign Policy.

When Israel announced it would enter Lebanon again on October 1, 2024, it cited the UN's failure to uphold the resolution as its casus belli.

Under the terms of the agreement, Israel cannot enforce the Resolution itself. But with 60,000 civilians displaced from northern Israel by the conflict, the government finds itself under huge pressure at home.

The 15 parties present in 2006 voted unanimously for the resolution. None voted against and none abstained.

The Israeli military also said Thursday that it had killed a senior Hezbollah militant, Mohammed Anisi, who was involved in the group's development of precision guided missiles. 

Anisi was killed in an airstrike targeting the group's intelligence branch in Beirut, the army said.

Meanwhile, Hezbollah said its fighters detonated a roadside bomb when Israeli forces entered the Lebanese border village of Maroun el-Ras, killing and wounding soldiers. 

It was not possible to independently confirm the claims made by either side.

So far, ground clashes between Israeli forces and Hezbollah militants have been confined to a narrow strip along the border.

But hundreds of thousands of people have fled their homes, as Israel has warned people to evacuate from dozens of villages and towns in the south, telling them to relocate to areas that are around 60 kilometers (36 miles) from the border and considerably farther north than the Litani River.

Under UN Security Council Resolution 1701, which ended the monthlong 2006 war between Israel and Hezbollah, the militants were to withdraw north of the Litani, and Lebanon's armed forces were to patrol the border region along with UN peacekeepers.

Neither Lebanon's army nor the peacekeepers were capable of imposing any agreement on Hezbollah by force, and Israel says it defied the resolution and built extensive military infrastructure in towns and villages near the border. 

Lebanon has accused Israel of violating other parts of the resolution.

Israel maintains that it is targeting Hezbollah after nearly a year of rocket attacks that began October 8 and displaced some 60,000 Israelis from communities in the north. 

Israel has carried out retaliatory strikes over the past year that have displaced tens of thousands on the Lebanese side.

Nearly 2,000 people have been killed and more than 9,000 wounded in Lebanon since the fighting began nearly a year ago.

The vast majority of recent strikes have been in areas where Hezbollah has a strong presence.

Iran-backed Houthi rebels in Yemen said they launched two drones at Tel Aviv overnight. The military said it identified two drones off the coast of the bustling metropolitan area, shooting one of them down while the other fell in the Mediterranean Sea.

Hezbollah, Hamas and the Houthis are part of the Iran-led Axis of Resistance, which also includes armed groups in Syria and Iraq. They have launched attacks on Israel in solidarity with the Palestinians, drawing retaliation in a cycle that has repeatedly threatened to set off a wider war.

Another flight carrying Britons from Lebanon arrived in the UK amid the spiralling conflict as G7 leaders urged regional players to act with 'restraint'.

The plane touched down in Birmingham on Thursday, a day after more than 150 British nationals and dependants left Beirut on the first Government-chartered flight as concerns mount over how long the capital's airport can remain open.

The Foreign Office said a 'limited number' of additional flights had been chartered, including the one which set off on Thursday heading for Britain.

Lebanon's Middle East Airlines is also continuing to operate its scheduled services from Beirut and Britons have been advised to get the first flight available out of the country.
