Hamas leader Ismail Haniyeh was killed in Iran on Wednesday, the Palestinian group Hamas and Iran's elite Revolutionary Guards said in separate statements.
Here are reactions:
Mohammad Ali Al-Houthu, head of Yemen's Houthi supreme revolutionary committee:
"Targeting Ismail Haniyeh is a heinous terrorist crime and a flagrant violation of laws and ideal values."
Sami Abu Zuhri, senior Hamas official:
"This assassination by the Israeli occupation of Brother Haniyeh is a grave escalation that aims to break the will of Hamas and the will of our people and achieve fake goals. We confirm that this escalation will fail to achieve its objectives.
"Hamas is a concept and an institution and not persons. Hamas will continue on this path regardless of the sacrifices and we are confident of victory."
