A picture taken on February 6, 2014, shows the Aleppo central prison during clashes between pro-Syrian regime soldiers and rebel fighters. Syrian troops retook most of Aleppo's prison, lost to rebels a day earlier, in fighting that has killed at least 46 people over two days, the Syrian Observatory for Human Rights said.
