People fleeing southern Lebanon are sleeping on the sides of roads as they head north, an aid worker tells the BBC's World At One.

Speaking from Marjayoun in the south-east of the country, Eva Homsi, an emergency coordinator and head of programming at Shield, says roads were blocked by the sheer number of people seeking safety.

She says it was "really hard" to see people sleeping in their parked cars and "on the road without blankets, without pillows, without mattresses, without food".

A combination of blocked roads and Israeli air strikes also meant supplies are not arriving, she says, adding that bread and medicine have not been delivered since Sunday.

In its latest operational update, the Israel Defense Forces (IDF) says its warplanes have attacked about 280 Hezbollah targets in Lebanon on Wednesday.

It says the targets included the launch platforms from where attacks were carried out on northern Israel in the morning, as well as weapons depots and other military infrastructure.

Among the sites attacked on Wednesday were 60 targets used by Hezbollah's intelligence, the IDF said in an earlier report.

At least 51 people were killed and more than 220 were injured in Israeli strikes on Lebanon on Wednesday, the Lebanese health minister says.

More than 90,000 people have been displaced in Lebanon since Monday, the United Nations says.

This is in addition to the 111,696 people have been displaced since October 2023.

An update from the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) also says that since Monday, nearly 600 people have been killed, including 50 children and 94 women.

Nearly 1,700 have been injured by strikes across Lebanon, it says, citing the Lebanese health ministry..

In northern Israel, around 70,000 people so far have been evacuated because of near-daily attacks by Hezbollah in Lebanon since October.

Hospitals in Lebanon are "very overwhelmed" after last week's attacks there, a medical aid charity says, as it expressed concerns that the country's healthcare system "will completely collapse".

Dr Tania Baban, country director of the medical charity MedGlobal Lebanon, tells the BBC's Newshour programme of how one school, which is being used as a temporary shelter, is "being flooded with injured patients and patients who are already sick with chronic illnesses".

"The hospitals are very overwhelmed, especially after last week’s attack…it’s really really reaching a brink and we are worried that the healthcare system will completely collapse," Dr Baban adds.

She referenced last week when pagers and walkie-talkies exploded across Lebanon killing dozens and injuring thousands.

The White House says it's "deeply concerned" after Hezbollah launched a missile towards towards Tel Aviv in Israel.

"It's certainly deeply concerning, obviously to the Israelis, of course, but also to us," the White House's national security council spokesman, John Kirby, said in an interview with CNN.

"There is still time and space for a diplomatic solution here to de-escalate the tensions and to prevent an all-out war."

Israel's army says it has launched strikes against 60 Hezbollah positions across Lebanon.

It says the attacks targeted sites used by Hezbollah's intelligence division, including headquarters and other infrastructure used in the gathering of intelligence.

According to a map released with the announcement, the majority of the sites were in southern Lebanon, though some were in the centre and northeast of the country and one was on its northwest coast.

UK Prime Minister Keir Starmer says he's "very worried" about the escalation of fighting in Lebanon, as he called for "all parties to step back from the brink" and "de-escalate".

"We need a ceasefire so this can be sorted out diplomatically," he adds.

Asked what his messages is for British nationals still in Lebanon, Starmer says: "The time to leave is now. Contingency plans are being ramped up, but don't wait for those.

"There are still commercial flights, it's very important that they hear my message, which is to leave, and leave immediately".

The Lebanese health ministry has been giving updates on the death toll which, as we have just reported, has risen.

Let's have a look at the locations of the towns across Lebanon where the ministry says people have been killed.

Seven people in Baalbek Hermel in the Beqaa Valley are known to have died while the next highest death toll is in Bint Jbeil, southern Lebanon- where the ministry says there are four fatalities.

Another four have been killed in Joun, located in the Chouf district, central Lebanon.

Three more were killed in Ain Qana, also in southern Lebanon, and earlier we told you three people died in the town of Al-Maaysra in Keserwan, north of Beirut.

Finally, we have had reports from the ministry that two people were killed earlier this morning In Tebnine.

Dozens of people were also injured in the strikes, according to the health ministry.

The Lebanese health ministry says 23 people are now known to have been killed after Israeli air strikes across various locations.

The United Nations Interim Force in Lebanon (Unifil) has described the current situation in the region as "very concerning".

"We're still working to try to de-escalate the tension - but the situation is definitely very unpredictable, very difficult," Unifil spokesperson Andrea Tenenti tells the BBC.

"We are still deployed, fully deployed in the south of Lebanon. But there is now a real need for a political and a diplomatic solution."

Unifil has 10,000 peacekeepers along the so-called Blue Line, dividing Lebanon from Israel and the Israeli-occupied Golan Heights.

Hezbollah likely retains massive weapons arsenalpublished at 13:12 British Summer Time 25 September

The missile that was launched by Hezbollah towards Tel Aviv was reportedly an Iranian-made Qadr-1, a medium-range ballistic missile that can carry a warhead of between 700kg and 1,000kg.

It would have been enough to destroy most or all of a sizable building, had it not been intercepted over central Israel by one of the country's multiple air defences, in this case a system called "David’s Sling".

Hezbollah has an arsenal of between 100,000 and 150,000 rockets, drones and missiles.

Up to 10,000 of these are believed to be medium-range, precision-guided ballistic missiles, like the Fateh-110, that can reach Tel Aviv and most of the population centres in Israel. (Jerusalem is considered a less likely target because of its large Palestinian population.)

Last month, Hezbollah released a video boasting of its vast, underground arsenal of these missiles, threatening to unleash them on Israel should war break out.

Israel’s "Operation Northern Arrows", launched this week, is seeking to destroy as much of this arsenal as possible, including where Israel says missiles have been concealed in private homes and garages.

But Hezbollah’s subterranean network of tunnels and caves, built into the hard rock of southern Lebanon, is extensive. Despite all the air strikes, it most likely retains the capability to fire a massive barrage of missiles at Israeli cities, but its leadership also knows the retaliation would be devastating for Lebanon.

It's just gone 13:00 in the UK and 15:00 in Israel and Lebanon, where at least 15 people were killed in a wave of "extensive" Israeli air strikes across southern and central Lebanon.

If you're just joining us, here's what else you need to know:

• Dozens of people were injured, according to the Lebanese health ministry, which says the strikes hit towns in central Lebanon, away from its border with Israel
• Earlier, Israel said it had intercepted a ballistic missile fired by Hezbollah towards Tel Aviv - the first such rocket to target the city

• The influential Shia armed group says it has fired "dozens of missiles" into northern Israel
• Firefighters in the region shared images that show the extent of the damage to buildings in the Safed area, where officials say no injuries were reported
• Thousands of people in Lebanon are on the move, heading north to escape the Israeli strikes in the south

US Secretary of State Antony Blinken just appeared on CBS News to talk about rising tensions in Lebanon following Israeli strikes.

He said the best way for people to return to their homes in southern Lebanon and northern Israel is not war but through "diplomacy".

"We're focused right now on making sure that we can de-escalate, avoid a full-scale war," Blinken said.

Blinken was also asked about ongoing ceasefire negotiations between Hamas and Israel and said that while there is an agreement, Hamas has not been engaged in talks in recent weeks.

"It still requires hard decisions on the part of Israel, but it is the best way to stop what's happening in Gaza, get the hostages out," he said.

"But also, as you said, it would help in the north. It would give an off ramp to Hezbollah to pull back and allow diplomacy to work."

I have just been to Beirut Airport - the only civilian airport in Lebanon.

Most flights are cancelled after international airlines have suspended their flights from and to Beirut.

Both arrivals and departure lounges are almost empty.

The MEA - Lebanon's national airline - as well as the Iraqi and Iranian airlines are the only companies still operating at the moment.

Many countries have issued urgent reminders for their nationals to leave Lebanon immediately.

But so far no government has mentioned any activation of their evacuation plans.

The BBC has witnessed Israeli air strikes around the city of Tyre, in southern Lebanon.

Orla Guerin visited the usually crowded holiday destination and says it is now "basically deserted", apart from people fleeing intense Israeli strikes in nearby towns.

In the past few days there have been many discussions in Lebanese media asking whether Iran is giving up on Hezbollah for the sake of its own benefit.

However, sources close to Hezbollah and high ranking members from Iran-backed Iraqi Shia paramilitary groups tell me such a thing is "impossible" and that "Hezbollah and Lebanon are red lines not only for Iran but also for other groups of axis of resistance."

Yesterday, Israeli media reported that more than 40,000 Houthis and Iraqi Shia paramilitary fighters may enter Lebanon soon. And today, Iraq's Popular Mobilisation Units - an umbrella organisation for many Iran-backed armed groups - has announced that they are sending food and other supplies "to support Lebanon".

For now it is expected that Iran leaves visible support for Hezbollah to its allied armed groups in the region, rather than declaring its own direct involvement. However on 30 July, Israel’s airstrike on Dahieh, in the southern suburbs of Beirut, killed an Iranian "adviser" alongside Hezbollah’s top commander Fuad Shukr.

That in itself showed that Iran is already giving on the ground support to its most important paramilitary ally in the region.

"Hezbollah is victorious," Iran's supreme leader posted on his official X account this morning, the first reaction from Ayatollah Ali Khamenei to Israel’s attacks on Lebanon and Hezbollah.

It comes amid speculation about Iran’s status on supporting Hezbollah - an influential Shia Muslim political party and armed group that has received strong backing from Iran, both financially and militarily, for many years. Especially when it seems Tehran is trying to de-escalate with the West and reach an agreement in nuclear negotiations.

Speaking in New York on Monday, Iranian President Masoud Pezeshkian said that Iran does not seek a wider war in the Middle East and that such a conflict would have no winners.

And in an interview with Reuters, UN nuclear watchdog chief Rafael Grossi said that he has sensed a greater willingness by Iranian officials to engage with the agency in a more meaningful way after talks in New York, and that he hopes to travel to Tehran in October.

All this raises questions on Iran’s stance, if Israel’s attacks on Hezbollah intensify and Lebanon enters an all out war.

The Israeli military says that it is carrying out air strikes in southern Lebanon’s Nabatieh town.

The IDF says it will provide further updates later.

Earlier, the Israeli military said it was carrying out "extensive strikes" in southern Lebanon. However, the Lebanese health ministry says some of those killed in Israeli air strikes today were in central and southern towns in the country.

The UK prime minister has told British nationals in Lebanon to "leave immediately" as fighting intensifies between Israel and Hezbollah.

Sir Keir Starmer said "we are ramping up the contingency plans, I think you'd expect that in light of the escalation” and warned that "we are potentially at a brink" of all-out war.

The UK's Ministry of Defence is sending 700 troops to nearby Cyprus to prepare for the possible evacuation of British nationals from Lebanon and the government "continues to advise against all travel to Lebanon".

An estimated 10,000 UK citizens are currently in Lebanon.

A number of other countries - including Australia, Canada, France, Japan, Saudi Arabia, South Korea and the US - have also urged their nationals to leave Lebanon.
