A Bradford expert in terrorism has warned that Britain is at real risk of terrorist strikes.

International security expert Professor Paul Rogers, 59, pictured, believes the war on terror has increased the likelihood of further paramilitary attacks and Britain could be a target.

The professor of the University of Bradford's Peace Studies department travelled the world meeting defence experts to compile research for his updated book, Losing Control.

In its first edition, published ten months before the attack on the World Trade Centre, he warned of the West's increasing vulnerability to paramilitary action.

He has now added a new chapter expressing fears of fresh attacks from terrorist organisations such as Al-Qaida.

"I wanted to update the book because many of the warnings in it have been borne out by events around the world," he said. "Now the situation has moved on and I feel we are going to see a lot more instability in the Middle East and a lot more paramilitary attacks on the West, possibly on the scale of September 11.

"Another attack could come at any time and it is a possibility that they may choose to hit an American installation in Britain."

Losing Control is the 16th book he has written since joining the university 22 years ago.

In it he warns of hardening militant attitudes in the Middle East as a result of an increasing scarcity in resources, a growing gap in the wealth of rich and poor nations and improving education in countries resentful of the West.

He also believes America's 'gung-ho' response to the atrocities in New York and Washington has stirred up support for militant groups in the Middle East.
