At least ten people were killed in shelling on the Syrian town of Douma, northeast of the capital Damascus, on Saturday, the Syrian Observatory for Human Rights watchdog said.

"Ten citizens were killed, a child and nine men... in the town of Douma as a result of shelling by regime forces," the group said in a statement, after earlier reporting air raids on the town.

Nearby, in the town of Moadamiyet al-Sham, the group reported air raids and tank fire, as well as shelling of the Barzeh district of the capital, which has been under fire for three straight days.

According to the Observatory, the area saw some of the worst fighting in more than two years between regime and rebel forces on Friday.

The area in the northeast of the capital is a residential neighbourhood and has been divided in two, with one side held by the regime and the other by rebel forces.

Elsewhere, regime forces carried out air raids against parts of Damascus and Aleppo province and strikes were also reported in western Latakia and southern Daraa.

On Friday, at least 127 people were killed in violence throughout the country, according to a toll from the Observatory, which relies on a vast network of activists and medical staff inside Syria.
