Majid Asgaripour/WANA (West Asia News Agency)People hold posters of Palestinian group Hamas' leader Ismail Haniyeh, during an anti-Israel gathering following the killing of him, amid the ongoing conflict between Israel and Hamas, in Tehran, Iran, Jul 31, 2024. Hamas' armed wing said in a statement Haniyeh's killing would "take the battle to new dimensions and have major repercussions". In Turkey, thousands of pro-Palestinian demonstrators marched through the streets of central Istanbul late on Wednesday to protest Haniyeh's killing. US Secretary of State Antony Blinken, in Singapore, sidestepped a question on Haniyeh's killing, saying a ceasefire deal in Gaza was key to avoiding wider regional escalation. Qatar, which along with Egypt has been brokering talks aimed at halting the fighting in Gaza, condemned Haniyeh's killing.
