Israeli officials said Israel launched an airstrike against senior Hamas political leaders in Doha, Qatar. The attack had been approved by President Trump.
Al-Arabiya reported that Hamas's chief negotiator was killed in the airstrike.
Israeli Defense Minister Katz had earlier warned Hamas leaders abroad that they would be annihilated if the group did not lay down its arms. Qatar called the attack a blatant violation of all international law and condemned Israel's "cowardly" attack on Hamas officials in Doha.
