Bolivia's President Evo Morales has condemned the U.S. President Donald Trump's threat to launch an attack against North Korea that the "world has never seen before", as an insult to humanity.
"This is an affront to all mankind," Morales said on Twitter.
He added "To the fire and to the fury of the threats from the USA, we must put before dialogue, peace and social justice."

Trump has warned Pyongyang he will respond with "fire and fury" if it continues to issue warnings to the United States.
He said the North Korean leader Kim Jong-Un has been "threatening beyond a normal state."
The Bolivian President called for the international community to reject his calls and unite against any type of war.
"The governments of the people of the world have a duty to oppose it. In these wars, the empire gains and the people lose," Morales said.
Trump's comments follow a Washington Post report which said that North Korea has successfully created a miniaturized nuclear war head.
In response, Pyongyang said it is "carefully examining" plans for a missile strike on the U.S. Pacific colony of Guam.
Korea was united before the U.S. war on the peninsula from 1950-1954 left the people on both sides of the border permanently divided.
The U.S. has over 37,500 troops stationed in South Korea.
Tensions often run high at this time of year as the U.S. and South Korean armed forces prepare for their annual joint military drills at the end August.
The U.N. Security Council unanimously imposed new sanctions on the DPRK at the weekend.
China, Pyongyang's closest ally, has described the situation as "complex and sensitive" and urged a return to dialogue.
