Hamas did not immediately comment on the Israeli military’s claim that Abu Obeida, one of the armed group’s best-known officials in the Arab world, had been killed.

One attack was an effort to assassinate Abu Obeida, one of Hamas’s best-known spokesmen, Israeli officials said. It was not immediately clear if that succeeded.

Abu Obeida, the spokesman of Hamas' Qassam Brigades, was killed in a Saturday strike on western Gaza City, Al Arabiya and Al Hadath reported, citing a Palestinian source.
