Lebanon’s official news agency said an Israeli strike killed six people including three children and the son of a militant in Lebanon’s largest Palestinian refugee camp, AFP reports.

A Palestinian camp official had told AFP earlier that an Israeli strike targeted the house of the son of a top Palestinian militant in the Ain al-Helweh camp on the outskirts of the southern city of Sidon.

“The Israeli raid targeted the house of the son of Mounir Maqdah” in the Ain al-Helweh camp, the official said, requesting anonymity to discuss sensitive matters.

It was unclear if Maqdah — who Israel has accused of heading the Lebanese branch of Fatah’s armed wing — was at the property.

The official National News Agency said his son Hassan Maqdah, his wife and four other people — a woman and three children — had been killed.
