Chilling footage captures the moment toxic gas engulfs an entire port killing ten and leaving hundreds injured.
A 25 tonne chlorine tank exploded with yellow-coloured gas at a dock in Jordan's Aqaba port injuring at least 251 workers - as dock worker tried desperately to flee the toxic scene.
The chlorine gas was being exported to Djibouti but a leak was caused during transportation, according to officials.
