Heavy fighting in and around the
Syrian capital Damascus has killed at least 40 people and wounded many more,
state media and observers say.
The Syrian Observatory for Human Rights said at least four children were
among 35 people killed in nearly 40 air raids on Thursday in a Damascus
province.
At least five people were also killed in a series of rebel mortar attacks on
the capital, state media report.
Rebels have vowed to avenge government attacks on the nearby town of Douma.
On Tuesday, Jaysh al-Islam (Army of Islam) leader Zahran Alloush said his
group now considered Damascus a "military zone"- the latest attacks on the
capital were apparently carried out by them.
