Israeli forces killed at least 11 Palestinians in separate strikes in the Gaza Strip on Thursday, medics said, hours after the military said it had hit the site of a failed militant rocket launch, the latest violence to jeopardize the ceasefire.

Medics said an Israeli airstrike killed at ?least four people and wounded three others, including children, in a tent in the western area of Khan Younis in the southern ?Gaza ?Strip. Another strike killed a person east of the city, near where Israeli forces operate.

Later on Thursday, medics ?said a man was killed in an Israeli strike on a school sheltering displaced families in Jabalia in northern Gaza, while another strike killed a person in a tent near Deir al-Balah in the central Gaza Strip.
