A man pulls a trolley containing belongings as a woman walks behind at the Karaj al-Hajez crossing, a passageway separating Aleppo's Bustan al-Qasr, which is under the rebels' control and Al-Masharqa neighbourhood, an area controlled by the regime February 4, 2014. Reuters photographs showed streets packed with Aleppo residents carrying large packs as they fled the home-made barrel bombs - oil drums or cylinders packed with explosives and metal fragments. Barrel bombs, cheap and easy to construct and usually dropped from helicopters, often kill dozens at a time. Activists say they are being used to push people from rebel-held areas into state-controlled parts of the city. REUTERS/Ammar Abdullah (SYRIA - Tags: POLITICS CIVIL UNREST CONFLICT)
