An explosion ripped apart a motorcycle in Gaza City early Sunday, residents said, killing three people - including a senior Hamas commander and his assistant.
Hamas charged that Israel was responsible for what it called a "dirty assassination crime" killing Wael Nassar, 38, a top Hamas commander, and his assistant, Mohammed Sarsour, 31, his assistant, and a bystander. The two Hamas leaders were on the motorcycle when it exploded, witnesses said.
It was not immediately clear what caused the explosion. Witnesses said they saw a flash in the sky and then the motorcycle exploded, indicating an Israeli missile strike. The residents said they did not see any Israeli helicopters in the sky, though they heard an unmanned Israeli plane.
