White House Announces Anti-Violence Summit as World Leaders March in France

Israeli Prime Minister Benjamin Netanyahu and Palestinian President Mahmoud Abbas are among the marchers.

About 1 million people marched in Paris on Sunday after France’s worst terror attack in more than half a century, including Israeli Prime Minister Benjamin Netanyahu, Palestinian President Mahmoud Abbas, U.K. Prime Minister David Cameron, German Chancellor Angela Merkel, and King Abdullah of Jordan. Ambassador to France Jane Hartley represented the U.S.

Elsewhere in the French capital on Sunday, Attorney General Eric Holder attended a terrorism security summit of the world’s top intelligence and law-enforcement officials at the French Interior Ministry to address mounting concerns about attacks like those in Paris last week. 

The White House said it was convening its own international forum on Feb. 18 to “highlight domestic and international efforts to prevent violent extremists and their supporters from radicalizing, recruiting, or inspiring individuals or groups in the U.S. and abroad to commit acts of violence.”

Alex Webb, Helene Fouquet, and Del Quentin Wilber contributed reporting.
