DHAKA: US President Barack Obama and British PM David Cameron have vowed to defeat the "distorted ideology" of terrorism, ahead of talks in Washington.

The UK and US leaders said they would not allow anyone to "muzzle free speech" after Islamist gunmen killed 17 people in terror attacks in Paris.

The BBC.com publishes the report on Thursday.

They are expected to discuss cyber crime and the economy during the prime minister's two-day visit.

It is likely to be his final Washington visit before May's general election.

Cameron is also expected to raise the case of Shaker Aamer, the final British resident in Guantanamo Bay.

The UK is seeking the return of Aamer, who has been held for 13 years without trial, to his family in Britain.
