An extremist group embroiled in infighting with one of the largest Syrian rebel groups has pledged allegiance to al-Qaida-linked militants, a move that threatens to deepen divisions in the already-disparate insurgency.

UK Foreign Secretary William Hague said the “right decision” had been reached after European Union foreign ministers agreed to end the embargo on supplying arms to opposition forces in Syria.

Syria’s main opposition coalition began a push yesterday to form an interim government to provide services to people living in parts of the country now controlled by rebel forces.
