Three people have died after they were hit by a train in south London, with police treating the deaths as unexplained.
British Transport Police were called to Loughborough Junction, a station on a busy commuter line near Brixton, where three people were pronounced dead at the scene.
Aerial footage showed the bodies, covered by white sheets, lying on an elevated part of the track that would not normally be accessible to the public.
"My team are now working hard to understand what happened and how these three people came to lose their life on the railway," Gary Richardson from British Transport Police said in a statement.
"My thoughts are with the family and friends of these three people.
"At this time, we are treating their death as unexplained as we make a number of immediate inquiries.
"I would ask anyone who was near to Loughborough Junction this morning, and saw something which they think might be relevant, please contact us as soon as possible."
Fatalities are relatively rare on Britain's rail network. Seven people died when a car pulled onto a rail crossing in 2004 in Berkshire, southern England, and seven died when a tram crashed in Croydon, south London in 2016.
Transport police said rail services would be delayed in the area while they investigated the scene.
