Israeli Prime Minister Benjamin Netanyahusaid on Wednesday Syria must be stripped of its chemical weapons and that the international community must make sure those who used weapons of mass destruction pay a price.

Netanyahu said Syria had carried out a "crime against humanity" by killing innocent civilians with chemical weapons and that Syria's ally Iran, who is at odds with the West over its nuclear program, was watching to see how the world acted.

"We must make sure that the Syrian regime is stripped of its chemical weapons, and the world must make sure that whoever uses weapons of mass destruction pays a price for it," Netanyahu said. "The message that is received in Syria will be received loudly in Iran."
