Caretaker Prime Minister Najib Mikati on Monday warned that his country was suffering an "unprecedented" crisis that threatens its existence, as Israel says it is waging war on Hezbollah.

"Lebanon is going through an unprecedented historical and existential crisis that threatens its present and future," he told a joint Arab League and Organization of Islamic Cooperation summit in Riyadh.

Saudi Arabia's de facto ruler called for immediate ceasefires in Gaza and Lebanon at a joint Arab League and Organization of Islamic Cooperation summit that will renew calls for a Palestinian state on Monday.

Arab and Muslim leaders gathered in Riyadh, more than a year into the Israel-Hamas war and regional escalation, in what is seen as a chance to send a message to U.S. president-elect Donald Trump.

Maronite Patriarch Beshara al-Rahi has called on Hezbollah to “draw lessons” from its current war with Israel.

On Saturday 9 November, the British Ambassador Hamish Cowell commemorated Remembrance Day. This annual event, which marks the end of the First World War on 11 November 1918, honors the sacrifice of the Armed Forces community from the UK and the Commonwealth and remembers innocent civilians who have lost their lives in conflict and acts of terrorism.

The British Ambassador, Hamish Cowell, was joined in giving a reading by the German Ambassador, Kurt Georg Stoeckl-Stillfried, the American Ambassador, Lisa Johnson, and the French Deputy Head of Mission, Bruno Pereira Da Silva.

Parliament Speaker Nabih Berri has reportedly said that Israel is acting “as if we have lost the war, but we have not been defeated.”

Hezbollah official Salim Ayyash, who was convicted by the Special Tribunal for Lebanon over the 2005 assassination of Rafik Hariri, has been killed in a recent Israeli strike in Syria’s Qusayr area, Arab and Israeli media reports said.

Israeli Foreign Minister Gideon Saar on Monday said there had been "certain progress" on a ceasefire in Lebanon after the Israeli army launched an operation in the country targeting Hezbollah.

"There is certain progress," Saar said in response to a question about a possible ceasefire. "We are working with the Americans on the issue," he told reporters in Jerusalem.

At least 41 people were killed in Israeli strikes across Lebanon on Sunday, including 23 in a raid north of the capital Beirut, the health ministry said.

Israel has intensified its air campaign in recent days, especially in the country's south and the southern suburbs of Beirut.

Israeli Prime Minister Benjamin Netanyahu said, in a first public disclosure, that he had okayed a September attack on Hezbollah in which hundreds of communication devices exploded across Lebanon.

"Netanyahu confirmed Sunday that he greenlighted the pager operation in Lebanon," his spokesman Omer Dostri told AFP of the attacks that killed nearly 40 people and wounded nearly 3,000, and preceded Israel’s ongoing military operation in Lebanon.

Curled up in his father's lap, clinging to his chest, Hussein Mikdad cried his heart out. The 4-year-old kicked his doctor with his intact foot and pushed him away with the arm that was not in a cast. "My Dad! My Dad!" Hussein said. "Make him leave me alone!" With eyes tearing up in relief and pain, the father reassured his son and pulled him closer.

Hussein and his father, Hassan, are the only survivors of their family after an Israeli airstrike last month on their Beirut neighborhood. The strike killed 18 people, including his mother, three siblings and six relatives.
