In news from Syria, the United Nations is warning that about half a million children are now trapped in besieged areas and are “almost completely cut off from sustained humanitarian aid and basic services.” The U.N. report estimates there are 100,000 trapped children in the rebel-held areas of Aleppo, which witnessed intense fighting over the weekend. According to the Syrian Observatory for Human Rights, two rebel-held areas of eastern Aleppo have fallen to government forces in what’s been described as the biggest defeat for the opposition in Aleppo since 2012.
