An Israeli missile strike on a car in Gaza City has killed four Palestinians, including a top Islamic Jihad commander.
Palestinian witnesses and the Israeli military both reported the strike Saturday. Relatives say the dead militant was Mohammed Dahdouh, a senior Islamic Jihad commander in Gaza. He and two women and a child were killed.
Earlier in Gaza City, a powerful explosion ripped through the headquarters of the Palestinian Intelligence Service, killing one person and wounding at least eight others, including the Palestinian intelligence chief.
Officials say the blast was an assassination attempt on the intelligence chief, General Tareq Abu Rajab.
So far, no one has claimed responsibility for the attack, but one intelligence official indicated that the militant group Hamas may have been responsible.
The blast comes at a time of growing tension between the Hamas-led government and the Palestinian security forces loyal to moderate President Mahmoud Abbas.
Mr. Abbas sent his intelligence chief to Jordan last week to investigate Jordanian suspicions that Hamas was trying to smuggle explosives into the kingdom to carry out attacks there.
