The former head of Israel’s intelligence agency Mossad defends the country’s treatment of al-Nusra Front fighters on the Syrian border.

In this web extra, Efraim Halevy tells Mehdi Hasan that he is not concerned that Israel had treated fighters in Syria from al-Nusra Front, which some say is al-Qaeda’s Syrian branch.

“It’s always useful […] to deal with your enemies in a humane way,” Halevy says.
