The US-sanctioned tanker Rich Starry re-entered the Strait of Hormuz on Wednesday after leaving the Gulf the previous day, as shipping data showed it was unable to pass a US-enforced blockade aimed at ships visiting Iranian ports.

“During the first 24 hours, no ships managed to get past the US blockade,” the US Central Command said on X, noting that six vessels followed instructions from US forces to turn back and head toward an Iranian port, The Caspian Post reports, citing foreign media.

The Chinese-owned tanker was among at least eight ships that had transited the waterway on Tuesday, marking the first day of the US blockade.

A US official also stated that a US destroyer intercepted two oil tankers attempting to depart from Iran’s Chabahar port in the Gulf of Oman on Tuesday.
