A Comorian-flagged oil tanker has capsized 25 nautical miles southeast of Oman's Ras Madrakah in Duqm port town, Omani News Agency (ONA) reported on Monday, citing the sultanate's Maritime Security Centre.
The centre said a search-and-rescue operation was activated in coordination with authorities.
Duqm has a prime geographical position at the heart of the Arabian Sea and stands at the crossroads between Asia and Africa.
