The funeral is under way of five young friends who died during a day trip to a beach.
Kenugen Saththiyanathan, 18, known as Ken, and his brother Kobikanthan Saththiyanathan, 22, known as Kobi, both of Normandy Way, Erith, south-east London, died at CamberSands, near Rye in East Sussex last month.
Their friends Nitharsan Ravi, 22, of Admaston Road, Plumstead, south-east London, Inthushan Sriskantharasa, 23, of Chadwell Road, Grays, Essex, and Gurushanth Srithavarajah, 27, of Elsa Road, Welling, south-east London, also died.
A Hindu ceremony and petal laying is taking place at Plumstead Common, south East London.
Relatives of some of the men have previously criticised the lack of lifeguards at Camber and suggested they may have stood a chance of survival if the beach had been manned.
Hundreds of mourners are at the service which started at dawn in Winn's Common Park.
Relatives and friends wept as the coffins were carried into marquee tents, before mourners walked around and paid their respects.
