In a statement released in Western media outlets, the group threatened to carry out more attacks. "The month of Ramadan is a month of holy war and death for Allah. It is a month for fighting the enemies of Allah and God's messenger, the Jews and their American facilitators."
Its statement said, "One of our groups aided by Allah managed to bomb a bus full of Jewish tourists, plunderers of holy lands, after careful tracking.
"The holy war is not confined to a particular arena and we shall fight the Jews and the Americans until they leave the land of Islam."
Israel and the US pointed a finger at Iran and Hezbollah following the attack.
