An Israeli airstrike slammed into a densely populated residential area in Lebanon’s capital near key government and diplomatic buildings late Monday, killing at least five people as the U.S. pressed ahead with cease-fire efforts. Lebanon’s state-run National News Agency said two missiles hit the area of Zoqaq al-Blat neighborhood – where local U.N. headquarters and Lebanon’s parliament and prime minister’s office are located. Since late September, Israel has dramatically escalated its bombardment of Lebanon, vowing to severely weaken the Iranian-backed Hezbollah militant group and end its barrages in Israel that the militants have said are in solidarity with Palestinians during the war in Gaza.
