Leader of Hamas in the Gaza Strip
Sinwar was born in a refugee camp in the Gaza enclave and spent at least 22 years of his adult life in Israeli prisons. He had been sentenced to life in 1989 for directing the killing of two Israeli soldiers and four Palestinians that he believed to be collaborators, having already made a name for himself as “the Butcher of Khan Yunis” for his hunting down of Palestinians he suspected to be working with Israel.
