TEHRAN, Iran (AP) — Iran‘s Revolutionary Guard said a short-range projectile was behind the killing of Hamas political chief Ismail Haniyeh and accused the United States of supporting the attack which it blamed on Israel, state TV reported Saturday.

The televised statement, which reiterated a call for retaliation, said a rocket with a seven-kilogram (about 15-pound) warhead was used to target the residence of Hamas’ political leader in the capital Tehran on Wednesday, adding it caused heavy devastation. It didn’t share details of the residence’s location.
