From an AP story by Najib Jobain, Samya Kullab, Ravi Nessman, and Matthew Lee headlined “After blast kills hundreds at Gaza hospital, Hamas and Israel trade blame as rage spreads in the region”:

A massive blast rocked a Gaza City hospital packed with wounded and other Palestinians seeking shelter Tuesday, killing hundreds of people, the Hamas-run Health Ministry said. Hamas blamed an Israeli airstrike, while the Israeli military blamed a rocket misfired by other Palestinian militants.

At least 500 people were killed, the ministry said.
