Mosab Hassan Yousef

Who is Mosab Hassan Yousef?

Mosab Hassan Yousef is a Palestinian and son of a Hamas founder and leader Sheikh Hassan Yousef. From 1997 to 2007, he worked undercover for Israel's internal security service Shin Bet, which considered him its most valuable source within the Hamas leadership.

According to Israeli sources, the information Yousef supplied prevented dozens of suicide attacks and assassinations of Israelis, exposed numerous Hamas cells, and assisted Israel in hunting down many militants, including his own father. In March 2010, he published his autobiography titled Son of Hamas.

Yousef has since converted to Christianity and moved to California. His request for political asylum in the United States was granted pending a routine background check on June 30, 2010.
