In contradiction to an earlier report circulated Sunday that the Islamic Jihad intended to stop Kassam rocket attacks on Israel provided that Israel cease its attack on launch sites in Gaza, the organization vowed Sunday to step up its attacks on Israel. "Islamic Jihad is going to escalate its attacks on the Zionist entity by all possible means," Khader Habib, an Islamic Jihad leader in Gaza, said. "We are going to teach the government of Tel Aviv a lesson they are not going to forget." Shortly before Habib spoke, Islamic Jihad members fired two rockets at the southern Israeli city of Ashkelon, the group said. The IDF could not confirm that any rockets had been fired Sunday afternoon.
