THE massive explosion which killed at least 100 people and left 4,000 injured in Lebanon's capital Beirut is feared to have been started by a reckless welder.
Shocking pictures show flattened buildings, the walking wounded, and a sea of rubble in the wake of the explosion which could be heard 110 miles away in Cyprus.
More than 2,750 tons of ammonium nitrate detonated when a blaze apparently spread to the warehouse where it had been stored for six years.
Security sources reportedly now claim a welder sparked the initial fire that in turn ignited the chemicals - causing a blast the fifth the size of Hiroshima.
Ammonium nitrate is mainly used as a fertilizer, but has also been linked to terror attacks after being used in homemade bombs.
General Security chief Abbas Ibrahim said it had been confiscated years earlier, reportedly from a ship.
Up to 250,000 people have been left homeless by the explosion which caused around £5bn of damage, say reports.
