US President Barack Obama has said the fight against violent extremism cannot be won by military power alone.
In an editorial for the Los Angeles Times, Mr Obama said the world must “confront… the propagandists, recruiters and enablers”.
He is due to speak to representatives of dozen of countries at White House event on extremism.
The event, originally planned for last year, is focused on local responses to prevent radicalisation.
UK Home Secretary Theresa May is among those expected to attend.
Mr Obama has asked Congress to formally authorise military force against the Islamic State (IS) military group in Iraq and Syria. The US and partners have carried out air strikes against the group since last year.

The US is also concerned about growing extremist involvement in Libya and West Africa, as well as Americans and Europeans who have joined IS.
The event also comes after the killing of 17 people in Paris by attackers motivated by not directly in contact with IS.
In the editorial, Mr Obama said groups like al-Qaeda and [IS] “exploit the anger that festers when people feel that injustice and corruption leave them with no chance of improving their lives.”
“The world has to offer today’s youth something better,” he said, adding “governments that deny human rights play into the hands of extremists”.
And Mr Obama referenced the recent murders of three Muslim students in North Carolina in the editorial.
“We do not yet know why three young people, who were Muslim Americans, were brutally killed in Chapel Hill, NC.”
“But we know that many Muslim Americans across our country are worried and afraid.”
