At least 21 killed, 100 wounded in bombing by Syria army of northern town - monitor

 At least 21 people were killed and around 100 wounded when Syrian army planes bombed a town in northern Syria that is controlled by Islamic State (ISIS) militants, a group monitoring the war said on Sunday.

Syrian military helicopters dropped barrel bombs and warplanes launched air strikes on al-Bab which lies northeast of the city of Aleppo, the Britain-based Syrian Observatory for Human Rights reported without saying when the attacks happened.

One of the 21 killed was a child and the death count was expected to rise as some of the wounded were in a serious condition, said the Observatory, which gathers information from a variety of sources in Syria.

US-led warplanes have also been hitting ISIS targets in Syria in a campaign which Washington says is not coordinated with Damascus. The Syrian army previously hit an area near al-Bab in September, saying it had "eliminated a number of terrorists" shortly after US-led strikes started.
