NEW YORK-- The United States ambassador to the United Nations urged the global body Monday to adopt the "strongest possible" sanctions against North Korea over its sixth and most powerful nuclear test.

Amb. Nikki Haley made the appeal during an emergency meeting of the U.N. Security Council that was convened after North Korea tested what it claimed to be an H-bomb on Sunday.

"To the members of the Security Council, I must say, 'enough is enough,'" she said. "The time has come to exhaust all of our diplomatic means before it's too late. We must now adopt the strongest possible measures."

She added, "Only the strongest sanctions will enable us to resolve this problem through diplomacy."
