Oman’s state news agency announced this on Monday and did not give further details.
Located just across the Strait of Hormuz from the Iranian territory at the entrance to the Persian Gulf, Oman has maintained friendly ties with Iran through successive crises in the region.
The cordial Tehran-Muscat relations have at times allowed the small but strategic sultanate to play an important mediating role, including with the United States.
Oman played a positive role in the preliminary nuclear negotiations between Iran and the Group 5+1 (Russia, China, the US, France, Britain and Germany) and hosted several rounds of the talks that ultimately led to a landmark 2015 deal between Iran and the major world powers.
