The 10-hour ceasefire by Russian and Syrian government forces in Aleppo has come to an end. Russia described it as a final chance for rebels to leave besieged areas. The rebels continued a counter-offensive aimed at breaking the siege, and Russia said two of its soldiers were wounded.<br/><br/>About 250,000 people are trapped in the east, amid food and medical shortages. Eastern Aleppo is the last major area held by rebels in Syria. If they leave, analysts say, it will be a big victory for President Bashar al-Assad in the five-year war.
