Rebel forces say they have taken full control of a scientific research centre in the Syrian city of Aleppo after a lengthy battle with government troops. Paul Chapman reports.
Video posted on a social media website purports to show Syrian rebels in action against government troops in Aleppo. The rebels are claiming victory in the battle to seize a scientific research centre in the Rashideen district. Aleppo was once Syria's most populous city before the nation's descent into civil war. Since 2012 it's been divided up into zones of government and insurgent control. The city is crucial to Syria's president. Losing it would further entrench the de facto partition of the country between the western areas still in government hands and the rest run by a patchwork of militia groups. An insurgent alliance including the al Qaeda-linked Nusra Front and hardline Islamist Ahrar al-Sham says it plans to 'liberate' Aleppo and govern it under sharia law.
