Videos posted on social media appear to show the aftermath of aerial strikes carried out by Syrian government forces and rebels in various cities across Syria.

The first video, said to be filmed in Idlib city, purports to show a young child being pulled from the rubble of her home by several men after what's said to be a government airstrike. She is then rushed to an ambulance, in the background men are heard shouting in Arabic "thank God she is alive."

On 12 April a group monitoring the Syrian war reported heavy air strikes in the northwestern province of Idlib, whose provincial capital was last month seized from government control by insurgent groups including the al Qaeda-linked Nusra Front.

The second video, said to be filmed on 16 April, appears to show thick smoke rising above several buildings in eastern Ghouta, a suburb of the capital Damascus, after shelling by rebel forces.

Another video, said to be filmed on 15 April, purports to show rebel mortar shells being fired on Syrian government targets in Aleppo, the largest city in Syria. Aleppo, near the Turkish border, is a major frontline in the Syrian war.

Rebel groups in and around the city have repelled repeated attempts by the Syrian army and militia fighting with it to cut supply lines from Turkey to the rebels.

Around 220,000 people have been killed during the four-year-old Syrian civil war, according to United Nations.
