Video uploaded to the internet appears to show rebels attacking government forces in separate locations across Syria.
Footage that has reportedly been shot in Aleppo on Thursday shows a tank exploding.
In another attack allegedly in the same area rebels appear to shell a government building.
While in another video what is believed to be a rebel fighter fires a machine gun at an airborne jet near Deraa.
Reuters cannot independently verify the footage of these attacks, which was obtained from a social media website.
But more than 100,000 people have been killed in the two and a half year civil war.
International efforts to resolve the conflict and eliminate Syria's chemical weapons continue.
