An international effort is under way to remove and destroy Syria's most dangerous chemical weapons.
The first consignment of Syrian chemical weapons materials left the country on a Danish ship on Tuesday.
The BBC's Anna Holligan spent time on board Norwegian vessel HNoMS Helge Ingstad, shortly before being removed following a media blackout.
Before she left the frigate, she filmed this piece about what life is like for the crew on board.
