North Korea on Sunday criticized for a second day a US decision to send tanks to Ukraine, calling it a “criminal act against humanity” aimed at perpetuating an unstable international situation.

Axar.az reports Washington’s allegations that North Korea has provided arms to Russia are a “baseless” effort to justify its own military aid to Ukraine, Kwon Chung-keun, director of US affairs at North Korea’s Ministry of Foreign Affairs, said in a statement carried by state news agency KCNA.

“The United States’ attempt to slam offensive armed equipment such as the main tank, into Ukraine, ignoring the legitimate concerns and condemnation of the international community, is a criminal act against humanity aimed at perpetuating the unstable international situation,” the statement said.

The baseless claims of North Korea-Russia arms deals are an “unacceptable and a grave provocation that must be responded to,” Kwon added.
