Last week, The New York Times reported that Israeli agents, at the behest of the US, had assassinated al Qaeda's number two on the streets of Tehran. Abu Muhammad al-Masri was gunned down along with his daughter, Miriam. She was also reportedly a target, as she was being groomed for a leadership role in al Qaeda. Iran has vehemently denied these reports. To shed some light on this story, we talk to Ronen Bergman. He's one of the writers of the piece and also the author of "Rise and Kill First: The Secret History of Israel's Targeted Assassinations".
