Israeli airstrikes hit Hamas sites in Gaza

Israeli military officials say they have struck four militant sites in the Gaza Strip after militants fired rockets into southern Israel, hitting a kindergarten.

There are no reports of injuries in either Gaza or the Israeli town of Sderot.

Israeli officials say their airstrikes took place early Saturday, targeting sites belonging to Gaza’s militant Hamas rulers.

Such attacks and counter attacks have occurred for the past two years.  The rockets fired from Gaza rarely hit building in Israel.
