Policemen block anti-war activists trying to hold their news conference demanding not to send South Korean troops to Afghanistan again, near the presidential Blue House in Seoul November 19, 2009, where U.S. President Barack Obama visited to hold a summit with his South Korean counterpart Lee Myung-bak. South Korea said at the end of October it would dispatch a security contingent of police and troops to Afghanistan to help support the U.S.-led mission there.
