Syria's president says his country will respect United Nations accords on chemical weapons.
At least nine people, mostly students, were reported to have been killed in an air strike on this school in north-eastern Syria.
The video, from a social media website and said to have been shot in Raqqa, could not be independently verified
The city's been under rebel control since March and is regularly targeted in air raids by government forces.
More video, said to be shot in Deraa, purportedly shows Syrian rebels taking positions and firing on government troops.
The images highlight the relentless nature of the civil war.
The fighting with conventional weapons rages on despite international steps to destroy Syria's chemical arsenal.
Syria's President, Bashar al-Assad, said in an interview on Saturday his country would respect United Nations accords on chemical weapons.
(SOUNDBITE)(English) SYRIAN PRESIDENT BASHAR AL-ASSAD SAYING:
"It's not about the resolution, it's about our will. Of course we have the will because in 2003 we had proposed in the United Nations Security Council to get rid of those weapons in the MIddle East, to have a chemical weapon-free zone in the Middle East."
The United Nations Security Council's adopted a resolution demanding the eradication of Syria's chemical weapons.
The resolution stopped short of threatening military strikes if Syria's government fails to comply.
