There are doubts emerging about whether Israel‘s strike in Doha, Qatar, on Tuesday that targeted senior Hamas leaders killed the people it intended to.

The strike targeted Hamas‘s chief negotiator, Khalil al Hayya, and others, but the group said it did not kill its negotiating delegation; instead, five lower-ranking members, including al Hayya’s son and his office director, were killed. The group hasn’t offered proof that he’s alive and has, in the past, said a leader was alive only to announce their deaths months later.
