Three ships used as floating armouries in the Indian Ocean have lost their flag over a suspected Russia-related sanctions breach.

St Kitts & Nevis said the three vessels were removed from its registry on 31 July after the UK government withdrew their licences to operate owing to the suspected breach.

The British government acted after a security company that stored weaponry with armoury operator MNG Maritime provided security services to a ship linked to Dubai-based Sun Ship Management.
