Yahya (Ibrahim Hassan) Sinwar was announced as the new head of Hamas's political bureau following the assassination of Ismail Haniyeh in Tehran - but his reign over the terror group was short-lived as the IDF announced on Thursday that he was killed in Rafah, in the southern Gaza Strip.

He was born on October 29, 1962, in the Khan Yunis refugee camp in Gaza. His family was displaced from Ashkelon during the 1948 Arab-Israeli War, a factor that profoundly influenced his militant activities and ideological commitments. 

Sinwar pursued his education at the Islamic University of Gaza, earning a degree in Arabic studies. His early life in the refugee camp instilled a solid determination to resist Israeli occupation, shaping his future role in Hamas.

How did Yahya Sinwar rise to prominence within Hamas?

Sinwar co-founded Majd, Hamas's security apparatus, in the late 1980s, focusing on identifying and eliminating Palestinians suspected of collaborating with Israel.

His terrorist activities led to his arrest in 1988 for orchestrating the abduction and killing of two Israeli soldiers.

Sinwar was sentenced to four life terms but was released in 2011 in a prisoner exchange deal for Israeli soldier Gilad Shalit. 

During his 22 years in Israeli prisons, Sinwar became known for his steadfastness and leadership among inmates, earning a reputation as a critical figure within Hamas.

What were Yahya Sinwar's key leadership roles and achievements?

In 2017, Sinwar was elected as the leader of Hamas in Gaza, succeeding Ismail Haniyeh. His leadership marked a shift towards a more militant stance, emphasizing military build-up and closer ties with regional powers like Iran and Hezbollah. 

Sinwar's strategic vision involved enhancing Hamas's military capabilities and preparing for large-scale conflicts with Israel. 

He is widely regarded as the mastermind behind the October 7 massacre against Israel, which resulted in over 1,200 deaths and the abduction of around 240 hostages.
