'My initial thought was the whole train would blow up' - man left with burn injuries after fireball explosion
A man injured in the explosion described the moment a fireball engulfed a London train, charring his head and leaving him in fear the entire vehicle would "blow up".
"Everyone ran off the Tube. It was panic stations - my initial thought was that the whole train would blow up," Peter Crowley told local radio.
"I saw passengers with facial burns, they had been exposed to a very, very hot fire for a nano second, it was lucky doors were open because everyone just got off the Tube.
"It was a terrifying experience, I am lucky I got away with just a bit of charred hair."
"I would personally say roughly about 20 who had physical injuries, a lot of people who were shaken by the incident.
"I wasn't aware of the bag, I tend to keep myself to myself, I was side on to where I believe the incident happened.
"That side of my hair is charred."
While the incident has been declared a terrorist incident by police Mr Crowley initially said he didn't "believe it was a terrorist attack, there was a lot [of] powder as if it was a high pressure tube that had some coating on it", he said.
The explosion occurred around 8.20am this morning on the packed commuter train at Parsons Green station.
A major investigation is underway and Prime Minister Theresa May is returning to Downing Street.
