Fighting in Aleppo, Syria, intensified Sunday after three days of ceasefire provided the desperate city a moment of relief. The unilateral ceasefire announced by Russia, which is supporting Syria's Bashar al-Assad regime, was not accepted by the rebels who control Aleppo and thus was swiftly broken.
Likewise, in Yemen, a three-day ceasefire ended Sunday, and the U.S.-supported, Saudi-led coalition intervening in the Gulf nation's civil war promptly resumed airstrikes. Each side of the conflict blamed the other for breaking the peace, and United Nations efforts to prolong the ceasefire were unsuccessful.
The brief truce did allow some humanitarian aid to enter the starving country, where nearly half a million children risk serious malnutrition.
