(KCEN) -- In Syria at least 21 people have been killed by aerial bombardment.
Footage posted online today shows a helicopter dropping a bomb on a town near the Turkish border.
Other footage apparently shows smoke rising over the area as the sound of gunfire rings out.
This video cannot be independently verified due to strict government controls on foreign media.
Other video too graphic to show on air shows three dead children.
Activists say the violence in Syria has now claimed more than 30,000 lives with no sign of letting up.
