Iran Revolutionary Guards Commander Ali Fadavi has threatened Iran will target Israeli energy and gas infrastructure if the IDF "commits terror" to attack Iran, the SNN News Agency reports.

"If the occupiers make such a mistake, we will target all their energy sources, installations and all refineries and gas fields," he said.

Iranian Foreign Minister Abbas Araghchi has vowed support for Tehran's "friends" in Lebanon while on his first visit to Beirut since fighting between Israel and Hezbollah militants intensified last month.

"Be sure that the Islamic Republic of Iran is and will be firmly standing by the friends in Lebanon," Araghchi told reporters, adding that Tehran supports Lebanon, its Shiite Muslim community and Hezbollah, "and it was necessary to say this in person".

Iran's most senior diplomat also said his presence in Beirut "in these difficult circumstances" was the best evidence that Iran stood by Lebanon and supported the Shi'ites.

He also backed efforts for a ceasefire in Lebanon, on the conditions Hezbollah also backed the ceasefire and it was agreed simultaneously with a ceasefire in Gaza.

"We support efforts for a ceasefire on the condition that it would be acceptable to the Lebanese people, acceptable to the resistance, and thirdly, it would be synchronized with a ceasefire in Gaza," he said.

The IDF says for the first time in two months, sirens are now sounding in southern Israel.

A delivery of medical supplies from the United Nations reached Lebanon today, a first since last week's escalation between Israel and Hezbollah, said a UN agency and a Lebanese minister.

"An airlift … landed in Beirut earlier this morning with 30 metric tonnes of trauma and surgical supplies, enough to treat tens of thousands [of] people," the World Health Organization's regional director Hanan Balkhy said on X.

"More flights are arriving later today and tomorrow, carrying trauma supplies, cholera supplies and mental health supplies."

Health Minister Firass Abiad was at the Beirut airport to receive the aid organised by the World Health Organization and UN refugee agency UNHCR and funded by the United Arab Emirates.

"We are receiving the first shipment out of many," he said.

The shipment included "many trauma kits that will be crucial to support the hospitals as they receive the casualties from the Israeli attacks on Lebanon", he added.

A UN refugee agency official says most of Lebanon's nearly 900 shelters are full and people fleeing Israeli strikes are increasingly sleeping out in the open.

"Most of the nearly 900 government established collective shelters in Lebanon have no more capacity," UNHCR's Rula Amin told a Geneva press briefing.

"With the onset of winter, UNHCR is concerned that conditions for those affected by the escalating conflict in other will only worsen."

"Roads are jammed with traffic, people are sleeping in public parks, on the street, the beach," Mathieu Luciano, the International Organization for Migration's office head in Lebanon, added.

He confirmed that most shelters were full, including those in Beirut and Mount Lebanon, but said some others still had space.

Many of the current shelters are schools, he said, meaning disruptions to education.

He voiced concern for tens of thousands of mostly female, live-in domestic workers in Lebanon whom he said were being "abandoned" by their employers. 

"They don't have papers ... and as a result, they are reluctant to seek humanitarian assistance because they fear that they may be arrested and they may be deported."

The agency also said that some people are fleeing on foot across Lebanon's main border with Syria, following an Israeli strike on the Masnaa crossing that connects the two countries by road.

"We could see that some people were walking, desperate to flee Lebanon, and so they walked actually through that destroyed road," Amin said.

"As they flee the bombings, families arrive with profound physical and emotional fatigue and huge needs for support."

Around 60 per cent of the more than 185,000 Amin said had arrived so far in Syria were children and adolescents, sometimes without their parents.

The Israeli military claims it struck an underground tunnel yesterday, which crossed from the Lebanese border into Syria and enabled the transfer and storage of large quantities of weapons.

"With precise intelligence guidance from the Military Intelligence Corps, yesterday, Air Force fighter jets attacked a 3.5 km long underground tunnel crossing the Lebanese-Syrian border that was used by Hezbollah to transport and store a large amount of weapons underground," IDF spokesperson Avichay Adraee wrote on X.

"As part of this attack, military buildings, weapons depots and other terrorist facilities were destroyed."

He also referenced the strike on the Masnaa border crossing, which we reported earlier today.

"Last night, infrastructure was also attacked at the Masnaa border crossing between Syria and Lebanon that was used to transport weapons to Hezbollah."

It is now 2:45pm in Lebanon. 

The IDF has claimed its strikes in Beirut yesterday targeted Hezbollah's intelligence headquarters and communications chief. 

Hezbollah says strikes have continued today, targeting a rescue worker attending to those wounded overnight.

These are a few photos which have come through across the day.

Hezbollah says an Israeli strike in south Beirut has killed a rescuer, accusing Israel of deliberately targeting civil defence teams.

After massive Israeli strikes overnight in Hezbollah's stronghold in the Lebanese capital, "Israeli aircraft targeted civil defence teams who were working to remove the rubble and rescue the wounded, leading to the death of a civil defence member," the group said in a statement.

Israel's military says it has eliminated the head of Hezbollah's communication networks, Mohammad Rashid Sakafi, by conducting a "precise, intelligence-based strike" in Beirut yesterday.

The claim comes after IDF spokesperson Avichay Adraee wrote on X that Israeli strikes on Beirut's southern suburbs yesterday targeted Hezbollah's central intelligence headquarters.
