American talk show host Charlie Wolf has recalled his shock at seeing soldiers on the streets of his country in the hours after the terrorist attacks of September 11, 2001.
Wolf, who has worked for various British media outlets and was living in the UK at the time of the attacks, spoke to talkRADIO as people around the world marked the 15th anniversary of the atrocities.
The broadcaster told Paul Ross: "I stumbled into the front room [and] put the TV on, and suddenly I see one of the towers of the World Trade Centre with smoke coming out of it.
"We had soldiers on our streets. There were military vehicles and every flight was grounded.
"What made it amazing was how a major story could exponentially jump up to an even greater story. It was something no one had ever seen before, essentially I was glued to that same chair for 8-10 hours."
Services were held across America yesterday to remember those who died in the attacks, which saw planes crash into the Twin Towers and the Pentagon and another flight crashland in Pennsylvania.
Six moments of silence were held in New York and Barack Obama held a moment of silence in the White House at 8:46am local time, which was the time the first plane hit the World Trade Center. He later spoke at the Pentagon.
