Prime Minister Gordon Brown has said Britain will not bow down to the continued threat of terrorism, as police arrest five people in connection with three thwarted attacks in the UK this week.

The new British premier addressed the media after a third attack saw a blazing car driven into the entrance of Glasgow Airport's terminal building in Scotland. The police have now said that the Glasgow attack is linked to the two attempted car bombs that were successfully defused in London in the early hours of Friday morning.

Overall five people are now being detained and questioned by police - two that escaped from the burning car at Glasgow airport, two in Cheshire, and a fifth person was recently arrested in Liverpool.
