Activists say that Syrian government airstrikes on a rebel-held neighborhood in the northern city of Aleppo have killed at least 25 people. Sunday marks the eighth consecutive day that the Syrian air force has bombed opposition areas of the divided city. The Britain-based Syrian Observatory for Human Rights says Sunday's air raids hit the Masaken Hanano district, including a second-hand market in the neighborhood. According to AP, observatory director Rami Abdurrahman says at least 25 people were killed. He says the death toll could rise because 17 of the wounded are in critical condition.
