Susan Elan Jones MP has been recalling the 7/7 London bombings that took place exactly 10 years ago today.
Susan Elan Jones MP said: "Unusually, on that day, I wasn't in the office as I was working at home on a research project. But right across London, there was the same eerie ambience - sounds of sirens, but virtually no vehicles moving.
"The thing that brought events home to me most was speaking to a work colleague, who had come out of the tube exit about 15 minutes before the bomb attack had taken place.
"In my view, every time politicians debate issues relating to civil liberties and surveillance, we need to do it through the prism of 7/7 and the need for proper security.
"I also believe we need to remember that people of many different nationalities. faiths and backgrounds were killed on 7/7 - and that our quest to understand people of different cultures is vital.
"This quest affects us every bit as much in North Wales as it does in London, and every other part of our country and our world."
