A man shot a police officer in Philadelphia on Thursday and said he did it to support the Islamic State terror group.

Officer Jesse Hartnett was hit multiple times after a 30-year-old man fired 13 shots into his vehicle.

Hartnett was wounded, but managed to return fire, striking the attacker multiple times.

Hartnett is expected to recover. He was shot three times in the arm.

The shooter was captured later by other Philadelphia officers.

Police released images from a security video showing the shooter taking aim at the police officer who sat in his police car. Police commissioner Richard Ross said "it's amazing he's alive."

Police Captain James Clark says after the shooter was captured, he pledged his allegiance to the Islamic State terror group.

Hartnett will require multiple surgeries to repair his gunshot wounds.

But Ross says "this could easily have been a police funeral."
