A special service has been held in Southampton to commemorate the lives of more than 600 African servicemen who died off the coast of the Isle of Wight during World War One.

The tragedy was South Africa's worst wartime naval disaster, and it happened exactly 99 years ago this weekend. The ship sank in thick fog, as Richard Slee reports.

The interviewees are Lt Col Rui Goncalves, Angolan Defence Attache; and Obed Mlaba, the South African High Commissioner.
