There was a movie made back in the early 1980's about this. I can't remember the name though.
Hope this helps:
"Sword of Gideon", directed by Michael Anderson and written by Chris Bryant, about a five-man commando unit unofficially sent out by the Israeli government to assassinate the 11 Palestinian terrorists identified as ringleaders in the murders of 11 Israeli Olympic team members.
