Oman's Environment Authority

Oman's Environment Authority logged oil along roughly 40km of coastline at Ras Madrakah on 13 August 2026 and warned that the slick was expected to reach Masirah Island, a sea-turtle nesting site further along the coast. The oil traces to Caroline Bezengi, a sanctioned tanker that ran aground in June carrying Russian crude, though the authority's role is response, not attribution.

The authority's own figures for the spill's extent sit inside a wider, unreconciled range of outside estimates, running from roughly 150 to 600 square kilometres. UK security firm Ambrey has reported an international cleanup response involving more than 100 tonnes of equipment, hampered by monsoon conditions.

Cross-border pollution incidents of this kind fall within the authority's ongoing REMIT, not a one-off task, so its coastal monitoring is likely to remain relevant well beyond this particular spill.
