Russian archaeologists believe they may have found the remains of two children of Russia's last tsar, executed by the Bolsheviks in 1918.
DNA tests will be carried out on the bones, thought to be those of Prince Alexei and his elder sister Maria.
Archaeologists excavated ground close to the site in Yekaterinburg where the tsar, his wife and their three other daughters were found in 1991.
Archaeologist Sergei Pogorelov says bullets found at the burial site indicate the children had been shot.
He told Russian television the newly unearthed bones belonged to two young people: a young male aged roughly 10-13 and a young woman about 18-23.
Ceramic vessels found nearby appear to have contained sulphuric acid, consistent with an account by one of the Bolshevik firing squad, who said that after shooting the family they doused the bodies in acid to destroy the flesh and prevent them becoming objects of veneration.
