Palestinian militants have fired more than 400 rockets into Israel while Israel has pressed ahead with a series of deadly air strikes on the Gaza strip and Egypt has began efforts to mediate an end to the fighting.
The Israeli military said it hit more than 130 targets, including rocket-launching sites, as blasts sounded across the Palestinian enclave.
At least three people were killed in a late-night bombing of a building in the southern Gaza area of Khan Younis, medical officials said. The target appeared to have been a senior Islamic Jihad militant, a source in the armed group said, but the identities of those killed were not immediately confirmed.
