BEIRUT (AP) — Israel has carried out a series of massive airstrikes overnight in the southern suburbs of Beirut. It had warned people to evacuate communities in southern Lebanon that are outside a United Nations-declared buffer zone. The blasts rocked Beirut’s southern suburbs, sending huge plumes of smoke and flames into the night sky and shaking buildings kilometers away. On Friday morning, Lebanese state media reported that an Israeli airstrike cut a main highway linking Lebanon with Syria. Also, Israeli forces carried out a strike Thursday in Tulkarem, a militant stronghold in the West Bank. The Palestinian Health Ministry said 18 people were killed in an Israeli strike on a refugee camp there.
