ISIS has claimed responsibility for the coordinated terrorist attacks across Paris on Friday that left 129 dead and 352 wounded, CNN reports.

According to a statement distributed on Saturday by ISIS supporters, eight assailants wore explosive belts and were armed with machine guns during the attacks on six separate Parisian areas. The attacks were a response to insults to the Prophet Mohammed and air strikes by France on ISIS targets, the statement said.

A Syrian passport was found near the body of one of the attackers. Seven of the attackers died in the explosions and the other was killed by authorities, according to police.

President Francois Hollande issued a televised address on Saturday in which he identified ISIS as the group behind the attacks and called it "an act of war."

"When the terrorists are capable of doing such acts, they must know that they will face a France very determined," he said.
