Israeli strikes on a stretch of Gaza filled with displaced residents killed at least 90 people on Saturday, according to the local health ministry, an attack Israel said had targeted top Hamas military commander Mohammed Deif.

       It was not clear whether Deif, who heads Hamas’s armed wing, the Izzedine al-Qassam Brigades, was killed in the strike. “There is still no absolute certainty” that Deif was among the dead, Israeli Prime Minister Benjamin Netanyahu said at a news conference Saturday. “But one way or another, we will reach every senior member of Hamas.”
