PM: Britain Will Not Yield
The prime minister was speaking to the BBC after Saturday's attack on Glasgow Airport was linked to the two car bombs found in London's West End on Friday.
Police are now holding five people over the attack on the airport and are searching houses near Glasgow.
The fifth person was arrested in Liverpool, Merseyside Police said.
Brown said it was "clear that we are dealing, in general terms, with people who are associated with al-Qaeda."
"It's obvious that we have a group of people - not just in this country, but round the world - who're prepared at any time to inflict what they want to be maximum damage on civilians, irrespective of the religion of these people who are killed or maimed are to be," he said.
Brown also praised the "magnificent work" of police and security services and the public for being vigilant and for helping prevent what could have been loss of life.
He said people still needed to be "constantly vigilant" against what was a "long-term and sustained threat".
"We have to fight it in a number of different ways - militarily, by security, by police, by intelligence," he added.
"And I think it's important to say also on a day like this - we've got to also fight it as a battle of hearts and minds.
"We've got to separate if you like those great moderate members of our community from a few extremists who wish to practise both violence and inflict maximum loss of life in the interests of a perversion of their religion."
He said: "We will not allow anyone to undermine our British way of life."
