The US has blocked two more shipping companies after their tankers allegedly delivered Venezuelan oil to Cuba.
The Office of Foreign Assets Control (OFAC) designated four ships in total.
It blacklisted Caroil Transport Marine of Cyprus, which operates three vessels that have now been sanctioned: the 16,900-dwt Carlota C (built 2010), the 74,000-dwt Sandino (built 2009) and the 73,000-dwt Petion (built 2006).
