The US accused Russia on Friday of violating U.N. sanctions on North Korea. Reuters reports the US cited “credible reports” that Moscow was granting new work permits to North Korean laborers, although Russia has denied doing so. The Trump administration also imposed U.S sanctions on a Russian bank it said facilitated transactions with a person blacklisted by Washington for involvement with North Korea’s nuclear weapons program. The Wall Street Journal says over 10,000 new North Korean workers have registered in Russia since September.
