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.

The attack on the Beddawi refugee camp near the northern city of Tripoli killed an official with Hamas’s military wing, along with his wife and two young daughters, the Palesitnian militant group said in a statement.
