Haniyeh, the Palestinian Hamas group's political chief, had resided in Doha along with other members of the Hamas political office. Haniyeh and a bodyguard were killed in the pre-dawn attack on their accommodation in Tehran early Wednesday, Iran's Revolutionary Guards said. The killings are the latest of several incidents that have inflamed regional tensions during the Gaza war which has drawn in Iran-backed groups in Syria, Lebanon, Iraq and Yemen. Reacting to Haniyeh's death, Qatar's prime minister said the killing had thrown the Gaza war mediation process into doubt. The international community called for calm and a focus on securing a ceasefire in Gaza -- which Haniyeh had accused Israel of obstructing.
