Hamas has appointed Yahya Sinwar as its new overall leader, replacing Ismail Haniyeh, who was recently assassinated in Iran. Sinwar, who masterminded the October 7 attacks against Israel, is viewed as a hardliner and has been running Hamas's military operations from hiding in Gaza. His leadership is seen as a defiance against Israel amid ongoing conflict, and he is expected to continue leading ceasefire negotiations, though experts suggest he may be less flexible than his predecessor. Israeli officials have reiterated their commitment to targeting Sinwar, further escalating tensions in the region. Foreign Minister Israel Katz claims that this leadership change underscores Iran's influence over the Palestinian issue. The U.S. has urged Sinwar to consider a ceasefire that could alleviate the humanitarian crisis in Gaza.
