A tourist boat exploded in northern Spain leaving 38 passengers injured, five of them in severe conditions.<br /><br />The footage, captured yesterday (July 25) off the coast of Grove in Pontevedra, shows flames engulfing the boat as a huge plume of grey smoke rises up into the air.<br /><br />A malfunctioning gas cylinder in the kitchen of the boat was the cause of the blast, reports say.
