At least 12 people were martyred and 30 wounded on Monday when terrorist militants fired on government-held districts of Syria's second city Aleppo.

“Rocket shells fired by terrorists fell in al-Jamiliyeh neighborhood and Baroun Street, killing 12 civilians, most of them are children,” SANA news agency quoted  a source at the Police Command of Aleppo as saying.

“Thirty other civilians were reported injured, while public and private properties in the sites sustained damage,” the agency added.

The bombardment was also reported by the Syrian Observatory for Human Rights, a Britain-based monitor, which put the death toll at 13.

The group reported at least 33 people wounded and said the death toll was expected to rise because of the number of seriously wounded.

The attack came a day after at least four people were killed in similar militants fire.

It also came as Human Rights Watch criticized opposition militants (both Takfiris and western-backed militants)  in a new report for indiscriminate attacks against civilians in government-controlled areas.

The Takfiri group, ISIL claimed responsibility on Saturday for a double bomb attack on Kurdish new year festivities which killed at least 45 people in the northeastern city of Hasakeh on Friday night.
