The wife and infant of Hamas’ top military commander, Mohammed Deif, died in what some believe was an Israeli attempt to kill him. Deif, long among Israel’s most wanted, is credited with designing Hamas’ Qassan rockets and leading the Islamist group’s military wing. The Israeli attack came after Gaza militants broke a cease-fire. Deif’s whereabouts remain unknown. By Wednesday morning, militants had fired more than 140 rockets into Israel. Cairo has tried to put together a peace deal, but the latest round of attacks offer little hope.
