Rebels shot down a Syrian army helicopter on Monday while it was bombarding the Damascus neighbourhood of Jobar, as heavy fighting broke out between rebels and troops loyal to President Bashar al-Assad in the district, witnesses said.
Syrian state television said in a news flash a helicopter had been downed in Damascus, but offered no further details.
The witnesses said the helicopter was engulfed in flames after it was hit by a projectile during a burst of gun fire and then came down in the nearby district of Qaboun.
Video footage taken by activists also showed a burning helicopter falling to the ground. Rebels on the ground could be heard shouting "God is greatest".
