Turkish border guards are accused of having shot and killed refugees fleeing Syria - including children.

The Syrian Observatory for Human Rights, a UK-based monitoring group, says that it happened at a border crossing north of the Syrian town of Jisr al-Shugour, which is controlled by jihadist groups.

The Turkish military insists guards fired only warning shots and that the Syrians dispersed.

The BBC has obtained footage from an activist at a hospital near the scene, who interviewed a woman who said five members of her family were shot.
