US-FILES-1993 WTC AFTERMA

(FILES) This file photo shows Brian Rolchford as he stands outside the World Trade Center after walking down from the 105th floor. Smoke swept through the 110-story building after an explosion caused the ceiling of a train station to collapse 26 February 1993. The explosion set off a fire below the twin towers. On 11 September 2001 two separate aircraft flew into the World Trade Center buildings in New York in what is suspected to be terrorist attacks. AFP PHOTO/Tim CLARY
