The threat from terrorists using chemical, biological and even nuclear weapons is growing, Britain said Tuesday, warning advances in technology will enable extremists to conduct more lethal attacks in the future.
The predictions came as Prime Minister Gordon Brown's government's laid out its anti-terrorism policies and strategy in a document containing previously-classified information.
In it the government also warned that although the al Qaeda organization of Osama bin Laden, was likely to fragment in coming years, the group's ideology will live on.
Under the strategy Britain, where 52 people were killed by home-grown Muslim extremists in July 2005 bomb attacks on London's transit network, says it needs to focus on longer-term causes of terrorism.
