The official Palestinian news agency, Wafa, said a woman and a child were among the wounded, describing the incident as a “drone strike”.

The Israeli military claimed two armed fighters were killed in a strike. “An Israeli air force aircraft attacked and eliminated two armed militants who posed a threat to the forces operating in the area” of Nablus, the military said in a statement.
