I have heard at least six loud explosions in Beirut.
Clouds of smoke are billowing over the southern suburbs, while drones buzz overhead.
Lebanese media reports that two strikes targeted locations in the Choueifat area, close to the airport, local media report, while three more hit other locations in the suburbs.
The Israel Defense Forces (IDF) has not commented.
This is becoming a routine for Beirut around midnight. First a heavy drone buzzing, then a warning from IDF and then after a round of explosions shake the whole town.
Live images show a large explosion in Beirut, after what appears to be a fresh Israeli attack on the city.
Little is known about exactly what was hit and the Israeli military is yet to comment. We'll bring you more as we have it.
Live pictures show smoke rising over Beirut, around an hour after the IDF called for residents in the city's southern suburbs to evacuate of some buildings.
We'll bring you more on this as we have it.
Israel says Hezbollah has fired more than 700 rockets across the border from southern Lebanon in the past four days.
Some missiles are being sent deeper into Israel than before as Hezbollah responds to the Israeli military’s ground offensive.

The Israeli military has issued new evacuation orders for a southern suburb of Beirut, because it says "Hezbollah facilities and interests" are located there.
The Israel Defense Forces (IDF) says buildings in Burj el Brajneh will be targeted "in the near future" and tells people living within 500m of them to move urgently.
That area, which is close to the airport, has already been hit by Israeli missiles today. The IDF has issued evacuation orders before many previous strikes.
Hezbollah has a strong presence in Beirut's southern suburbs. Most strikes in recent days have targeted that area.

The families of some of those who are still being held, as well as those who’ve been killed, were invited to address the crowd. “Bring them home," they chanted, waving placards bearing the faces of hostages.
Those demonstrating are furious at Prime Minister Benjamin Netanyahu and believe he is putting his own political ambitions ahead of the lives of Israeli hostages.
A year ago, Israel was united in its revulsion at what Hamas did on 7 October.
Twelve months on, its public, politicians and military are very much divided over the strategy in Gaza.

“You know my home was destroyed today," says Sameer, 26, with a little smile on his face.
He is working at one of my favourite Lebanese restaurants in Beirut’s famous Gemmayzeh street, which is full of coffee shops, restaurants and bars.
“I am happy that my family and I moved a few days before from there.”
Sameer’s home was in Burj el Brajneh, an area in southern Beirut hit by a series of Israeli strikes today. The IDF says it was targeting Hezbollah infrastructure.
Two buildings next to his family home have collapsed, he says, while his own is so badly damaged "it's no longer liveable".
He says his family has nothing to do with Hezbollah or any political party.
The restaurant was previously always full, especially on Saturdays. Tonight, just two tables are occupied – one by my journalist friend and I, the other by the owner and his family playing cards.
The many empty chairs are another sign of how much has changed in Beirut over the past few weeks.
Many restaurants and bars like this one were badly damaged in the port explosion four years ago. Only recently had the street had begun to get back on its feet.
“It’s like we just go back to square one over and over,” the owner, Mohammed, says.
Tonight, Gemmayzeh is empty. It’s dark, most places are closed.
Billboards that once read “Lebanon doesn’t want war” have been replaced by those reading “Pray for Lebanon”.
Outside one of few shisha bars still open, a screen that once played music videos until late now shows rolling news.

He describes it as "one of the largest ballistic missile attacks in history."
He continues: “No country in the world would accept such an attack on its cities and citizens, and Israel will not accept it either.
"Israel has the duty and the right to defend itself and respond to these attacks - and we will do so.”
Israeli military spokesman Daniel Hagari says 440 Hezbollah fighters have been killed since the start of Israel's ground invasion into southern Lebanon on Monday night.
He says that includes 30 commanders.
Hezbollah has not said how many of its members have been killed.
The Israel Defense Forces (IDF) says it will respond to Iran's "disgraceful" missile attack on Israel at a location and time of its choosing.
In a televised update, spokesman Daniel Hagari also confirms two Israeli air bases were hit in the attack on Tuesday, but remain fully operational.

The Middle East is once again on the brink of a much wider and more damaging conflict than those fires already blazing in Lebanon, Gaza and elsewhere.
Much now depends on how Israel intends to follow through on its well-publicised promise to "make Iran pay a heavy price" for its recent volley of ballistic missiles.
If Israel does hit back hard at Iran – and many are asking it not to – then the Islamic Republic has vowed to retaliate in turn, not just against Israel but also against those countries it sees as supporting it.
That could put US and British military bases at risk of attack, in the Gulf or even in Cyprus, which Iran’s long-range Ghadr-1 missiles can reach.
With hopes dimming of any imminent ceasefire in either Gaza or Lebanon, Israel appears determined to take on all enemies at once, with qualified backing from the US and Britain. Militarily, it is stronger than any of its adversaries, but wars started rarely end quickly.
Nearly one year on from Hamas’s 7 October attacks, Israeli forces are still in Gaza. Israel’s occupation of Lebanon lasted 18 years.
And a prolonged and direct conflict with Iran could have any number of unknown consequences for the region, and for the wider world.

The Israeli military is "preparing a response" to an Iranian missile attack against Israel earlier this week, an Israeli official told AFP news agency.
The military official, who spoke on the condition of anonymity, didn't provide further details on the nature or timing of the response.
Iran fired almost 200 ballistic missiles, external at Israel on Tuesday evening in support of Hezbollah. The Israeli military said most of the missiles were intercepted, but that a small number struck central and southern Israel. A Palestinian man in the occupied West Bank was killed.
The barrage followed Israeli air strikes targeting Hezbollah, including one which killed the group's leader Hassan Nasrallah in Beirut on 27 September.
Israel has previously warned of "consequences" for the Iranian attack and has discussed possible retaliation options with the US.

The southern Beirut neighbourhood of Dahieh was rocked by Israeli airstrikes again on Saturday, with no apparent warning given to residents ahead of time.
Footage posted on social media and verified by the BBC shows severe damage over two blocks in the Burj el Brajneh area, as well as injured and bloodied residents.
The IDF published its own aerial footage of the strikes taken from one of the aircraft involved in the bombing.
Dahieh has come under near daily bombardment since Israel assassinated Hezbollah's leader Hassan Nasrallah there on 27 September. Unconfirmed reports suggest Nasrallah’s potential successor was killed in another strike on the neighbourhood on Thursday night.
A senior member of staff at Al Rassoul Al-Azam Hospital, which sits about 800m from where one of the strikes hit on Saturday, tells the BBC that the detonation reverberated through the building.
The employee, speaking on condition of anonymity, says he has not been able to count the number of wounded because the ambulances were “coming one after another”.
A spokesman for the Lebanese Ministry of Health says the death toll and number of wounded from the day’s strikes had not yet been calculated but would be published later on Saturday.
If you're just joining us, here are the main developments we've been covering today in the Israel-Hezbollah conflict:
Hezbollah has fired 90 rockets into Israel so far today, according to the Israeli military.
It says 30 projectiles were fired into the Upper and Central Galilee area at around 14:09 local time, the majority of which were intercepted.
At around 14:52 another 30 were fired into Upper Galilee.
Earlier, a BBC reporter on the border heard a rocket explode within 100m of where our team was reporting from.

People across Israel are waiting to see how their government will respond to Tuesday’s Iranian missile strike, after both Israel and the US warned of “consequences”.
Shelley Barkan, a teacher in the north of the country, said by WhatsApp message: “On the one hand we have to respond harshly but of course as a civilian I’m afraid of the outcome.
“I hope that the IDF in cooperation with the Americans will make the most logical decision.”
She said people in the north had long been “living from day to day”. But, she added, “after the last Iranian strike, it made me even more proud to be living in Israel”.
A 64-year-old aircraft engineer in Jerusalem, who asked not to be named, said Iran’s action on Tuesday was “clearly and unequivocally a declaration of war” - but, he said, it needed a “smart response”.
“The response should be such that it would not lead to an endless ping pong, and that's the challenge.”
Inbal, 32, a psychologist in Tel Aviv, said the missile strike was “very stressful”, adding: “I don't think Israel can turn a blind eye to that, even though I am worried about the escalation that would just keep coming and tired of all these wars.
"I think Israel should again show its impressive strength with very precise, sophisticated actions.”

The president of Lebanon’s Order of Pharmacists has asked civil defence rescue teams to retrieve medicines from shuttered pharmacies in areas under Israeli bombardment.
Dr Joe Salloum tells the BBC he made the request after about 500 pharmacies closed, leaving some parts of the country dangerously low on vital drugs.
The affected areas are the south of Lebanon, the Dahieh suburb in southern Beirut, and the Beqaa valley, he says – all areas hit by Israeli strikes.
The shortages are threatening the lives of patients with chronic heart conditions, diabetes, hypertension and other illnesses, Salloum says.
“If the situation continues as it is we are going to have very bad shortages,” he says.
“We have emergency stocks of medicine, of course, but with hundreds or thousands of pharmacies closing down, those stocks can run out very fast.”

The United Nations (UN) High Commissioner for Refugees, Filippo Grandi, landed in Beirut this afternoon.
Posting on social media, he says Lebanon is facing a “terrible” refugee crisis, with people “left destitute or displaced by Israeli air strikes".
More than 1,110 people have been killed in Israeli strikes since 23 September, according to Lebanese authorities, with more than 1.2 million people displaced by the ongoing fighting.
