Defence Secretary Jim Mattis says North Korea's latest failed missile launch was a reckless act of provocation.
Mattis commented on the weekend missile launch in an interview with reporters travelling with him today to Saudi Arabia, where he begins a weeklong Mideast tour. His language was stronger than in an initial written statement he issued shortly after the launch, in which he simply said he was aware of the failure.
"The leader of North Korea again recklessly tried to provoke something by launching a missile," he said.
Mattis did not identify the type of missile but said it was not of intercontinental range, meaning it could not reach US territory. He did not comment on what might have caused the missile to fail.
Mattis credited China with trying to help get the North Korea situation "under control" with the goal of denuclearising the Korean Peninsula.
Asked about his visit to Saudi Arabia, Mattis said the desert kingdom is a "pillar of our security framework for the region."
The US military is providing support for a Saudi-led coalition fighting anti-government Houthi rebels, but Mattis said the US focus is on arranging a United Nations-brokered negotiating team to resolve Yemen's civil war diplomatically.
"This is something, with the number of innocent people dying inside Yemen, that simply has to be brought to an end," he said.
The US security alliance with Saudi Arabia, dating to 1944 and based largely on the Saudis' oil riches, has made Washington the kingdom's most important arms supplier.
