Moment boat explodes in fireball and sets other boats alight

Dramatic moment boat 'explodes' in a fireball before drifting into other vessels and setting them alight in busy marina. Video footage captured the moment a huge fire tore through boats in a busy marina as they 'exploded several times', leaving two people hospitalised.

The footage, which appears to be taken from a bridge, shows two boats on fire in Hampstead Marina at Yalding in Kent with huge clouds of thick black billowing smoke.
