Israel's Air Force bombed a weapons manufacturing site and a weapons storage facility in the northern Gaza Strip.
The early Tuesday morning strikes were in retaliation for recent rocket attacks on southern Israel, the Israel Defense Forces said in a statement.
Three Kassam rockets struck Sderot and its environs on Monday, one as schoolchildren were arriving at school for the first day of classes. On Sunday, three rockets were fired at southern Israel, hitting two factories, one in Sderot and one in the Sha'ar Hanegev Regional Council. Both were damaged.
The fundamentalist Salafi organization Jamiat ul-Mujahedin Bayt al-Maqdis late on Sunday claimed responsibility for the three rockets fired that day. The organization is affiliated with al-Qaida and is believed to be operating in the Gaza Strip.
"The IDF will not tolerate any attempt by terrorist groups to target Israeli civilians and IDF soldiers, and will continue to operate against those who use terror against the State of Israel. The Hamas terror organization is solely responsible for any terrorist activity emanating from the Gaza Strip," the IDF said in a statement.
