On 27 January 2002, Lagos, Nigeria's commercial capital, witnessed one of the biggest disasters that have ever hit the state and country. 20 years after, the memory is still fresh. A continued blast at the military cantonment in Ikeja left many dead. The bulk of the victims did not die under the exploding shells. Most were hauled from canals into which they jumped or were driven - some still in their cars - by the huge crowds fleeing the shrapnel descending from the sky.
