People gather in Capital to condemn the assassination of Ismail Haniyeh.


A source with knowledge of the negotiations told CNN on Wednesday that Haniyeh’s death could “complicate mediation talks.”

The source said Haniyeh – along with Hamas’ military leader in Gaza, Yahya Sinwar – was a “key decision maker.”

“He was someone who saw the value of a deal and was instrumental to getting certain breakthroughs in the talks,” the source added.

Haniyeh was in touch with mediators in Qatar and Egypt as recently as early July. Those talks now hang in the balance, despite some hope earlier this month that they were nearing a framework agreement.

“How can mediation succeed when one party assassinates the negotiator on other side?” Qatar’s Prime Minister Mohammed bin Abdulrahman Al-Thani, a mediator in the talks, posted on X on Wednesday. Qatar’s capital, Doha, also hosts the main Hamas political bureau.
