North Korea warned that it was prepared to take the 'toughest' action unless United States ended its 'military hysteria'.
Washington DC (United States): US Defense Secretary James Mattis has said that President Donald Trump and his military advisors have been briefed on North Korea's apparent failed missile launch.
"The president and his military team are aware of North Korea's most recent unsuccessful missile launch," Sputnik quoted Mattis as saying in a statement.
However, President Trump has not yet commented on the failed missile launch.
Earlier, North Korea's attempt to launch a missile on its east coast has apparently failed, US and South Korean defence officials said.
CNN quoted a South Korean defence official as saying that the missile launch was carried out from North Korea's Sinpo region in South Hamgyong Province.
Last month, a ballistic missile was also test fired by North Korea from the same site.
South Korean and US intelligence officials are trying to determine the type of missile used by North Korea for this launch.
US Pacific Command said it tracked a missile launch which blew up almost immediately.
The attempts came a day after North Korea begun its vast military parade to celebrate the birth of its founding father, Kim Il-sung, and warned that it was prepared to take the "toughest" action unless the United States ended its "military hysteria", The Guardian reported.
