The Syrian terror group al-Nusra Front says that its leader has been killed by a U.S. airstrike.
A statement from the group says Abu Yousef al-Turki was killed overnight in U.S.-led airstrikes in Syria. CNN cannot independently verify al-Nusra's claims, but the Syrian Observatory for Human Rights, a¬†monitoring group, says the group was among those targeted during the airstrikes.
Former U.S. Ambassador to the United Nations for Management and Reform, Mark Wallace, is OutFront. Wallace has just launched the counter extremism project, a not-for-profit group working to expose and disrupt sources of funding for extremist groups.

According to a U.S. official, Khorasan, an al Qaeda-linked organization, was ready to blow up commercial flights.
