Refinitiv data shows detained Grace 1 still at anchor

LONDON, Aug 17 (Reuters) - Refinitiv tracking data briefly showed the Iranian tanker at the centre of a diplomatic dispute between Tehran and the West had changed its position status off Gibraltar on Saturday.

The Grace 1 was given permission to leave Gibraltar on Thursday, although the United States is still seeking to detain it. Refinitiv data showed its status had changed to underway but by 1200 GMT it said the vessel was at anchor still. (Reporting by Kate Holton Editing by Gareth Jones)
