In Syria, the Assad government and Russia are continuing a devastating bombing campaign against the city of Aleppo for the fourth straight day. As many as 100 people have died since Friday. Witnesses describe it as the worst assault in the five-year civil war. United Nations Secretary-General Ban Ki-moon has expressed outrage at reports the Russians have begun using so-called bunker-busting bombs, which can destroy underground shelters and are so powerful they leave deep craters in their wake. This is U.S. Ambassador to the United Nations Samantha Power speaking Sunday.

Samantha Power: “Russia and Assad have reportedly launched more than 150 airstrikes over the last 72 hours, killing at least 139 people and injuring hundreds more, laying waste to what is left of an iconic Middle Eastern city. These are people who have suffered horribly in the five-and-a-half years of war, yet they call the attacks from the air unprecedented in quantity and quality.”
