Islamic Jihad fired three Kassam rockets at Israel on Saturday, one of which scored a direct hit on a house in Sderot, Israel Radio reported. Nobody was hurt in the incident. The rocket fire came a day after Israeli undercover forces in the West Bank killed three Islamic Jihad members in a firefight. The gunmen were driving in a car and were followed by the Israeli forces when the gun battle erupted. A local Islamic Jihad radio station in Gaza said the group's Al Quds Brigades fired the rockets in response to the killing of its members.
