A fire which broke out at a 19th Century cathedral in the Russian city of St Petersburg has brought down its main blue dome, officials say.
The blaze at the Trinity Cathedral, which started in scaffolding surrounding the main dome, also destroyed one of four smaller domes.
Dozens of firefighters were involved in efforts to put it out.
Icons and other religious artefacts have been rescued from the cathedral. There are no reports of injuries.
The Russian Orthodox Cathedral was built in 1835 and is a listed building.
