Palestinian President Mahmud Abbas condemned the assassination of Hamas leader Ismail Haniyeh, calling it a 'cowardly act' and urging Palestinian unity against Israeli occupation. Haniyeh was killed in Tehran after a projectile struck his residence during a visit for the inauguration of Iran's new president. Iranian authorities are investigating the incident, which has sparked outrage among Palestinian factions, leading to calls for strikes and protests. Hamas officials vowed retaliation, asserting that the assassination aims to undermine their will and the Palestinian cause. Meanwhile, the Iranian Supreme National Security Council is deliberating their response, emphasizing that Haniyeh's death will not be in vain. The U.S. acknowledged awareness of the assassination but refrained from further comment, while tensions in the region remain high.
