Additional evidence is cited in the article:
“[J]jihadists claimed on social media that Al-Nasr had been killed.
Other photos published by the terrorist organization show the alleged graves of Al-Nasr and two other militants who were killed in an airstrike.
The death of Sanafi Al-Nasr, whose real name was Abdul Mohsen Abdallah Ibrahim Al-Charekh, was also confirmed by the Britain-based Syrian Observatory for Human Rights, who claimed the jihadist leader was killed on Thursday.”
Al Qaeda Takes a Lead in Syria, US Sends Money Without Any Accounting

Nasr is a bin Laden cousin and a trusted player in al Qaeda. His brothers are long-time terrorists and two were in GITMO. They were released by George Bush and later attempted to commit an act of terrorism against US interests in Saudi Arabia. They were arrested in that country and little has been heard of them since.

SSG has allies in U.S. Sens. John McCain and Lindsey Graham on the Republican side, and Bob Casey, Robert Menendez, and Dianne Feinstein, who chairs the Senate Intelligence Committee, on the Democratic side and in the White House.
SSG is supposedly a conduit for a flow of information from the Supreme Military Council and the US government. They also lobby Congress for aid money.
The British Foreign Office has demanded that SSG repay thousands of pounds it was granted by the UK because the money was improperly spent. The US just sends money.
