Some nations are expelling North Korean ambassadors after the country's latest nuclear test.
On Monday, Spain declared its North Korean ambassador "persona non grata," giving him until the end of September to leave.
That follows similar moves by Mexico, Peru and Kuwait.
And unnamed officials confirmed Sunday that Kuwait is expelling an ambassador and other diplomats from North Korea.
Despite internationally backed sanctions from the United Nations, North Korea says it plans to continue developing its nuclear and missile programs.
