US President Barack Obama and British Prime Minister David Cameron say strong economies and democratic institutions will defeat "those who think they can muzzle freedom of speech and expression with violence."
In a joint article for the Times of London newspaper, the two leaders say that "our ability to defend our freedoms is rooted in our economic strength and the values that we cherish," and it is important "to bolster our economies against another global economic downturn."
Cameron is meeting Obama in Washington today for talks, expected to focus on cyber security and counter-terrorism in the wake of gun attacks in Paris that killed 17 people.
Cameron has said intelligence agencies need new powers to monitor online activity, and wants stronger cooperation from US-based companies such as Facebook and Twitter.
