Pressure in the region have been steadily rising since U.S. President Donald Trump pulled out of the Iran nuclear agreement and imposed strict sanctions on the country.
Tensions have been running high for months with ships attacked in the region, drones downed and oil tankers seized.
Shana, the news agency of Iran's oil ministry, denied the attack, saying "the tanker in question was completely stable."
The Defense Department announced Friday the deployment of 3,000 USA troops to the kingdom of Saudi Arabia "to assure and enhance the defense of Saudi Arabia".
It said the Sinopa was in the Red Sea, according the latest data updated on October 10. That vessel last turned on its tracking devices in August near the Iranian port city of Bandar Abbas. While Yemen's Houthi rebels, who have an on-going war with the kingdom since 2015, claimed the attack, numerous officials and analysts pointed at Tehran. He did not elaborate. The kingdom helped the Happiness 1 reach anchorage off Jiddah, where it was repaired and later left.
It follows attacks on vessels near the Strait of Hormuz, the shooting down of a U.S. military surveillance drone and other incidents across the wider Middle East.
The cause of the accident for the oil tanker is still unclear but the oil spill to the sea has been controlled, Sardashti added.
