In a significant escalation of the war in the Middle East, Israel targeted leaders of Hamas in a strike today in Qatar’s capital, Doha. Hamas said the attack had failed to kill its senior officials, but confirmed that the son of its chief negotiator, his office manager and three other people affiliated with Hamas were killed.

By directly striking in Qatar, a close U.S. ally and a primary mediator in talks to end the fighting in Gaza, Israel risked destabilizing the push for a cease-fire. Qatari officials condemned the attack, which they said had targeted a residential headquarters where senior Hamas politicians lived.

President Trump said the U.S. was told in advance about the strike. He added that it was unfortunate that the attack was in Qatar, but described the destruction of Hamas as a “worthy” goal.
