Gordon Brown has unveiled a raft of new measures to combat terrorism, with a twin-track approach aimed at tightening security and winning "hearts and minds".
Following a report by the Prime Minister's security minister Admiral Lord West into safety in public places, Mr Brown announced that barriers will be built outside airports, railway stations and ports while new security advice will be sent to cinemas, theatres, restaurants and sports stadia.
At the same time, a new unit will attempt to counter extremist propoganda, particularly in schools and universities, and to identify anyone at risk of falling under the influence of terrorists.
A forum of headteachers will advise on how young people can be protected from extremists, and how to build bridges between faith communities.
Restrictions at airports could be relaxed from early January.
