Iranian missile attacks have killed three Palestinian women in the occupied West Bank and a foreign worker in central Israel, medics said, AFP reports.

Falling shrapnel struck a hair salon in the West Bank town of Beit Awa near Hebron late Wednesday, killing the three women, according to the Palestine Red Crescent Society, marking the first Palestinian deaths from Iranian attacks in the ongoing Middle East war.

The victims include 17-year-old Mays Ghazi Masalmeh, according to the official Palestinian news agency, Wafa.

The Red Crescent said at least eight others were wounded, including one woman in critical condition. Wafa reported that the salon had been set up in a metal caravan next to a house.

AFP images showed civil defence workers inside the caravan, whose roof appeared to be punctured by the falling munition. A rug and bed sheets were covered in blood.
