US and UK join forces to combat extremists
Britain and the United States are to establish a new joint group to counter the rise of violent extremism in the wake of the Paris terror attacks, David Cameron and Barack Obama have announced.
Following talks in the White House with the US President, the Prime Minister said they were determined to confront the "poisonous and fanatical ideology" of the extremists wherever it occurred.
He said the new UK-US group would look at what more they could do to identify and counter the threat in their own countries, while learning from each other's experience.
At the same time, Britain is to step up its support to Iraqi forces fighting Islamic State (IS) terrorists with the deployment of additional intelligence and surveillance assets.
"Britain and America both face threats to our national security from people who hate what our countries stand for and are determined to do us harm," Mr Cameron told a joint press conference with Mr Obama.
"In recent weeks, we have seen appalling attacks in Paris, in Peshawar, in Nigeria. The world is sickened by this terrorism.
"So we will not be standing alone in this fight. We know what we are up against. And we know how we will win.
"We face a poisonous and fanatical ideology that wants to pervert one of the world's major religions - Islam - and create conflict, terror and death. With our allies, we will confront it wherever it appears.
"But, most important of all, we must also fight this poisonous ideology, starting at home."
Cyber-hackers pose a "real threat" to the City of London, Mr Cameron said, confirming this will be part of the "unprecedented" deal to tackle network attacks with Mr Obama.
A cyber-cell of British and American intelligence and security agents will be created as part of the agreement being backed by the Prime Minister and US president.
