The US and Britain are losing their war on terror, according to a British academic report published today.

Professor Paul Rogers claims military action in Afghanistan and Iraq has rallied, rather than crushed, the efforts of al-Qaeda.

The report, written for the Oxford Research Group, claims the military response to the attacks on the World Trade Centre and the Pentagon two years ago has caused more problems than it has solved.

The author has been Professor of Peace Studies at Bradford University for the past eight years.

His controversial conclusions come amid growing disquiet in Washington and London about the financial cost of the continuing occupation of Iraq and the growing list of US and British casualties.

The report says that since the 11 September attacks, more than 350 people have been killed and over 1,000 injured in attacks linked to al-Qaeda.

On that basis alone, he says, it is difficult to accept any claim that the war on terror is being won.
