BEIRUT — Syrian government airstrikes on a residential neighborhood in a rebel-held town killed over 40 people and wounded at least 100 others including many women and children, international watchdog Human Rights Watch said Thursday.

The strikes on the town of Azaz in northern Syria a day earlier leveled the better part of a poor neighborhood and sent panicked civilians fleeing for cover. So many were wounded that the local hospital locked its doors, directing residents to drive to the nearby Turkish border so the injured could be treated on the other side.

Reporters from The Associated Press saw nine bodies in the bombings' immediate aftermath, including a baby.
