At least 12 people are dead after a ferry ran aground and took on water off Indonesia's coast, forcing terrified passengers to leap into the sea and wait for rescue.

Passengers snapped dramatic photos as they clung to railings onboard the sinking vessel which was carrying up to 139 people and didn't have enough life jackets for everyone.
