A CHESHAM mother-of-two has told how she was almost blown up in Edgware Road Station last week after getting off a tube just seconds before it was targeted by terrorists.

Genevieve Kavanagh, 40, from Darvell Drive, had just arrived at Edgware Road from Baker Street, and had started walking up the station steps to the foyer area when she heard a loud bang coming from the platform as the bomb went off on the train.

She said: "It was a massive explosion.

"I have never heard anything like that before in my life.

"I turned around and saw metal and paper flying about."

Mrs Kavanagh, a maths teacher at North Westminster Community School, said one of her students was at the scene and tried to go back and find out what was going on.

"He asked me what was happening and I said I didn't know. He tried to go back but I dragged him away."

Mrs Kavanagh said that she was badly shaken by the bomb but told how she was puzzled as to what actually had happened.

She headed for the exit along with the student and called her husband, David, who told her initial reports suggested a "power surge".

Mrs Kavanagh said the tube train had moved around 200 to 300 yards away from the platform before the bomb went off.

But some of the carriages were still in the platform when it happened.

Mrs Kavanagh, who had been in the second carriage of the train, headed back into work yesterday on a Chilterns train from Chesham to Marlyebone.

She said: "I kept thinking who was on the train who might have done this.

"I thank God for giving me a second chance."
