Brussels Metro Survivor Describes 'Blanketed Thud' and 'Cloud of Dust' After Explosion

At least 21 people were killed in the subway bombing.

— -- A man who barely escaped today's deadly attack in a Brussels metro car said the explosion was "like a blanketed thud, and a cloud of dust rose up into the air."

Ian McCafferty said he was walking up to the ground level when "there was one loud thud and a shake."

He said when he reached "the top of the stairs and saw the soldiers eagerly evacuating the metro station," that was when "a little more panic kicked in."

McCafferty said he had jumped off the metro just a stop away from where the explosion took place.

The explosion happened at 9:11 a.m. local time, a spokesperson for Brussels public transport said, just as a five-car train was leaving the station and heading towards center of the city.
