Ahmed Yassin, co-founder and leader of the Palestinian Sunni Islamist group Hamas, two bodyguards, and nine civilian bystanders are killed in the Gaza Strip when hit by Israeli Air Force Hellfire missiles.

Sheikh Ahmed Ismail Hassan Yassin was a Palestinian politician and imam who founded Hamas, an Islamist political and military organization. He also served as the first chairman of the Hamas Shura Council and de facto leader of Hamas since its inception from December 1987 until his assassination in March 2004.

Palestinians are an Arab ethnonational group native to the Levantine region of Palestine. They represent a highly homogeneous community who share one cultural and ethnic identity, speak Palestinian Arabic and share close religious, linguistic, and cultural ties with other Levantine Arabs.

Sunni Islam is the largest branch of Islam and the largest religious denomination in the world. It holds that Muhammad did not appoint any successor and that his closest companion Abu Bakr rightfully succeeded him as the caliph of the Muslim community, being appointed at the meeting of Saqifa. This contrasts with the Shia view, which holds that Muhammad appointed Ali ibn Abi Talib as his successor. Nevertheless, Sunnis revere Ali, along with Abu Bakr, Umar and Uthman as 'rightly-guided caliphs'.

The Islamic Resistance Movement, abbreviated Hamas, is a Palestinian nationalist Sunni Islamist political organisation with a military wing, the Qassam Brigades. It has governed the Israeli-occupied Gaza Strip since 2007.

The Gaza Strip, also known simply as Gaza, is the smaller of the two Palestinian territories, the other being the West Bank, that make up the State of Palestine in the Southern Levant region of West Asia. Inhabited by mostly Palestinian refugees and their descendants, Gaza is one of the most densely populated territories in the world. An end of 2024 estimate puts the population of the Strip at 2.1 million, which was a 6% decline from the previous year due to the Gaza war. Gaza is bordered by Egypt on the southwest and Israel on the east and north. Its capital and largest city is Gaza City.
