U.S. Ambassador to the United Nations Nikki Haley warned on Sunday that the world body has "exhausted" its options on the Korean Peninsula nuclear issue.
"We have pretty much exhausted all the things that we can do at the Security Council at this point," Haley said in an interview with the CNN.
"None of us want war," she said, adding that if diplomacy fails on the nuclear issue, U.S. Defense Secretary Jim Mattis "will take care of it."
Meanwhile, the United States and South Korea have agreed to increase pressure on the Democratic People's Republic of Korea (DPRK) after its latest missile test, the White House said on Sunday.
U.S. President Donald Trump and South Korean President Moon Jae-in spoke on Saturday by phone and committed to "continuing to take steps to strengthen deterrence and defense capabilities and to maximize economic and diplomatic pressure" on the DPRK, according to a White House statement.
The DPRK confirmed that it conducted another medium-range ballistic missile test on Friday.
The missile launch, which violates U.N. Security Council resolutions, came just days after the council imposed fresh sanctions on the DPRK over its nuclear test on Sept. 3.
China on Friday said it opposes ballistic missile launches by the DPRK, urging all parties concerned to exercise restraint and avoid any acts that may escalate tensions on the Korean Peninsula.
