Holder: White House to Host Global Security Summit Feb. 18

President Barack Obama will invite allies to a Feb. 18 security summit in Washington, U.S. Attorney General Eric Holder announced on Sunday after meeting his European counterparts in Paris.

"We will bring together all of our allies to discuss ways in which we can counteract this violent extremism that exists around the world," Holder told reporters.

The Paris meeting of justice and interior chiefs came as France mourned 17 victims of Islamist gunmen this week in the worst assault on its homeland security in decades.
