DHAKA: The US has opened a three-day summit on countering violent extremism.

Representatives from around the world are attending the gathering, which follows shooting incidents in Denmark, France and Australia.

US vice-president Joe Biden said it was imperative to engage with immigrants who may be radicalised because of marginalisation.

‘Societies have to provide an affirmative alternative for immigrant communities,’ he said, reports the BBC.

The vice president said that countries needed to provide ‘a sense of belonging that discredits the terrorist's appeal to fear, isolation, hatred and resentment’.

The White House believes Europe is especially susceptible to terror attacks because immigrants there are often less well integrated into society.
