An Israeli strike on a refugee camp in north Lebanon has killed Hamas official Saeed Atallah Ali and his family, the militant group said Saturday. Hamas later said another military wing member was killed in an Israeli strike in Lebanon’s eastern Bekaa Valley.

Israel has repeatedly targeted Hamas and Hezbollah officials in Lebanon since the Gaza war erupted almost a year ago.

An Israeli strike hit Lebanon's northern city of Tripoli for the first time early on Saturday, a Lebanese security source said, after more bombardment hit Beirut's suburbs and Israeli troops sought to make new ground incursions into southern Lebanon.
