Lebanon's Prime Minister Najib Mikati said he wanted to boost troop numbers in the south to secure any ceasefire deal. Mikati said the international community had engaged in 'serious efforts' to impose a ceasefire, which he said the Iran-backed militant group had already accepted. His comments come as war-torn Lebanon strives for an end to hostilities after Israel on September 23 launched an intense air campaign mainly targeting Hezbollah in Lebanon, nearly a year into regular cross-border fire over the Gaza war. At least 1,315 people have been killed since Israel intensified its bombardment of Lebanon, according to an AFP tally of health ministry figures, though the real number is likely higher. Mikati said security had been tightened at the country's only airport in Beirut, to remove any potential justification for an Israeli attack. On Monday, Israeli Prime Minister Benjamin Netanyahu vowed 'to mercilessly strike Hezbollah in all parts of Lebanon -- including Beirut' a day after the Iran-backed group's deadliest strike on Israel since the start of the war in late September.
