Gaza Health Ministry spokesman Adham Abu Salmiya says the airstrikes overnight lightly wounded eight Palestinians. He says one strike set fire to a Health Ministry medicine warehouse in northern Gaza.
Israel's military said Wednesday that the strikes were in response to the firing of five rockets and mortars into Israel on Tuesday. The military said aircraft targeted a tunnel and two other sites used by militants.
The Hamas militants who rule Gaza have largely refrained from attacking Israel since Israel's Gaza offensive two years ago. But smaller groups continue to fire rockets and mortars.
