US SECRETARY of State John Kerry appeared yesterday to back Syrian extremists who stormed out of Geneva peace talks.

His comments came a day after Syrian troops — backed by Russian air strikes — broke Nusra Front lines north of Aleppo city to lift the three-year siege of the pocket of resistance around Zahraa.

The High Negotiating Committee (HNC) — a Saudi-convened delegation from dozens of the al-Qaida affiliate’s terrorist allies — responded by walking away from the already stalled negotiations.
