He says that according to the U.S. State Department, the three weren't accredited members of North Korea's UN Mission and had no diplomatic immunity.
USA officials on Friday forcibly confiscated a diplomatic package being carried by a member of the North Korean delegation, as they passed through US customs screening after landing at John F. Kennedy International Airport, Reuters reports.
A U.S. Department of Homeland Security spokesman told News 4 NY that the three individuals weren't accredited members of North Korea's UN Mission and had no diplomatic immunity. "The package in question had no diplomatic protection from inspection", said DHS spokesperson David Lapan in an e-mailed statement to International Business Times Monday.
The spokesman, who was not named as per usual KCNA practice, said North Korea "regards this mugging by the U.S. as an intolerable act of infringement upon the sovereignty" of its country, and demanded an explanation and an apology.
The agency's officers seized multiple media items and packages from them.
An article in the state-run news site said: "The U.S. literally mugged a delegation of DPRK diplomats at the airport" and they "behaved like a lawless, gangster state".

Comey also said Trump repeatedly sought assurances that he wasn't a target of the Russian Federation investigation. Baker's views didn't change, even as Comey told Trump a second and third time that he was not being investigated.
The spokesman said the North Koreans were carrying a valid diplomatic courier certificate. "This clearly shows that the U.S. is a felonious and lawless gangster state". The U.S. Department of State said it was looking into the situation but offered no immediate comment.
North Korea still holds three American prisoners.
President Donald Trump has repeatedly said he isn't seeking regime change in North Korea and hasn't ruled out negotiations to curb North Korea's rapidly advancing nuclear and ballistic-missile programs.
"Besides, North Korea is known the world over for using diplomatic pouches for illicit smuggling".
Last week, North Korea returned USA university student Otto Warmbier to his family in a coma, more than a year after he was sentenced to 15 years' hard labour for stealing a propaganda item.
Mr. Warmbier was arrested as he was attempting to leave Pyongyang that year, charged with committing "hostile acts" against the regime after stealing a propaganda poster from his hotel.
North Korea claims that Warmbier went into a coma after contracting botulism and was given a sleeping pill.
