Syrians shout slogans during an anti-regime protest in the rebel-held Bustan al-Qasr district in eastern Aleppo on May 5, 2016. The Syrian army said late on May 4 that it had agreed to calls from Russia and the United States for a two-day truce in Aleppo that would begin from 1:00 am on May 5. Renewed fighting in recent days, especially in and around Aleppo, had threatened the full collapse of the February 27 ceasefire agreement, a landmark in attempts to finally resolve a conflict that has left more than 270,000 dead. / AFP / KARAM AL-MASRI (Photo credit should read KARAM AL-MASRI/AFP/Getty Images)
