The US sanctioned a Ukrainian captain and his United Arab Emirates-operated tanker on Monday over his alleged role in oil cargoes to fund Houthi weapon purchases for attacks on commercial shipping.

Vyacheslav Salyga, 52, was in charge of the 105,900-dwt Otaria (built 2000) when it loaded commodities on behalf of a shipping network run by an alleged Houthi financier, according to the US sanctions regulator.
