U.S. Ambassador to the United Nations Nikki Haley tells the U.N. Security Council that North Korean leader Kim Jong Un is "begging for war," with the latest nuclear test that Pyongyang says is its first fusion device, a much more powerful weapon than it has exploded in the past.
"Enough is enough. War is never something the United States wants. We don't want it now. But our country's patience is not unlimited," Haley told an emergency session of the 15-member Security Council in New York.
