David Cameron has announced new laws to combat extremism, after warning of the growing threat of Islamic State to the UK's security.
While the UK had already taken steps to tackle the issue, more action was needed to fill "gaps in our armoury", Mr Cameron said.
He said new legislation would be introduced to seize passports and to ensure authorities can prosecute people for all terrorist activity including when it is overseas.
The PM wants to confiscate passports. But in Cardiff they want to solve extremism at it's roots - they just can't get the help to do it.
David Cameron has unveiled a series of new measures to combat the threat of terrorism.
Rumours suggesting London's Tube network will be targeted in a terrorist attack on Monday are "completely untrue", police say.
