Pakistani Prime Minister Shehbaz Sherif announced early Wednesday that a two-week Iran-U.S. ceasefire would also include Lebanon.

Three U.N peacekeepers who died in two separate incidents in Lebanon in March were likely killed by Israeli tank fire in one case and by a Hezbollah improvised explosive device (IED) in the other, according to a United Nations probe.

At a church in the mountains outside Beirut, Raymonda Mouawad raged as she buried her brother, killed by an Israeli strike in a war against Hezbollah that he had nothing to do with.

"We shouldn't be forced to bear the guilt of others' mistakes," she said, her voice filled with anger and sorrow.

An aid convoy organized by the Vatican envoy to Lebanon headed for Christian villages in the country's south had to turn back on Tuesday after it came under fire, a security source told AFP.

Apostolic Nuncio Paolo Borgia, who was travelling in the convoy, was being escorted by French peacekeepers from the United Nations Interim Force in Lebanon (UNIFIL), and was en route to the village of Debl near the Israeli border, the source told AFP on condition of anonymity.

The Israeli military on Tuesday urged all vessels in the maritime zone off the coast of southern Lebanon to immediately head north of the city of Tyre, warning that it would operate in the area.

Lebanon's health ministry said Tuesday that the death toll in more than a month of war between Israel and Hezbollah had reached 1,530.

President Joseph Aoun said Tuesday that he will not allow strike to occur in war-hit Lebanon. "Anyone attempting to fuel such a trend — whether through social media or media outlets — poses a danger to Lebanon and is committing an act worse than the Israeli attacks," he said, adding that no one can afford to endure internal strife.

"During my term, I will not allow anyone to accuse (Christian) citizens who remained steadfast in their villages and towns (in south Lebanon) of collaboration or treason," Aoun said, calling again for negotiations to end the Israeli war.

The Israeli military said on Tuesday it had completed the deployment of ground troops along a "defense line" in southern Lebanon, where it is fighting Hezbollah.

A Lebanese military source said the Israeli army had advanced to a depth of between five and nine kilometers inside Lebanese territory.

Hezbollah reported "fierce clashes" between its fighters and Israeli soldiers in Bint Jbeil on Tuesday, as Israel said it had completed the deployment of ground troops in south Lebanon.

The group said it targeted overnight into Tuesday troops and Merkava tanks in Bint Jbeil and other towns near the border.

The Israeli army struck and bombed overnight into Tuesday several towns and villages in south Lebanon after it issued an evacuation warning for more than 40 southern Lebanese towns.

Strikes and shelling hit Jwaya, Beit Yahoun, Jennata, Jmayjmeh, Hanaway, Majdalzoun, Wadi al-Hujair, Zebdine, Deir al-Zahrani, Maarakeh, Yohmor-Shqif, Arab Salim, Tebnine, al-Hosh, Kfardounin, Betoulay, Sreereh, al-Qatrani, Henniyyeh, al-Qlayleh, Tayr Debba, Sultanieh, Ain Baal, Mayfadoun, Barish, Wadi Sinai, Safad al-Battikh, Shaqra, Burj Qalaway, Tebnine, Baraashit and Haddatha. At least five people were killed in the strikes.
