US Central Command said that Iran's Revolutionary Guard (IRGC) approached one of the tankers hit with explosion earlier Kokuka Courageous and removed an unexploded limpet mine, attaching a video that what it says shows it, Reuters reported.
The low-quality footage, released by the US Central Command late on Thursday, showed a group of people in a boat next to some vessel. However, no flags or vessel names can be clearly seen in the video.

In a statement, released together with the footage, the military says the US forces had received two distress calls from Altair and Kokuka Courageous at 6:12 a.m. (01:42 GMT) and 07:00 a.m. on Thursday. USS Bainbridge destroyer began moving toward the tankers, while US airplanes observed vessels allegedly belonging to the Iranian Islamic Revolutionary Guard Corps (IRGC) in the vicinity of Altair, according to the statement.
Limpet mines are naval explosives attached to vessels by magnets.
Earlier in the day, Iranian IRNA news agency reported that the country's rescue services saved 44 sailors from tankers after a reported attack and took them to the Iranian port of Jask.
Kokuka Courageous tanker and another oil tanker, Front Altair, were hit by explosions in the Gulf of Oman near the Strait of Hormuz.
US Secretary of State Mike Pompeo said that the United States believes that Iran was behind the attacks, claiming that the assessment was based on intelligence, weapons used, and level of expertise needed to execute the operation.
Iran's mission to the United Nations has rejected the US claim that Tehran was responsible for attacks, saying it was unfounded.
