Two members of the Russian punk band Pussy Riot are still missing after disappearing while returning to Moscow from Crimea on Tuesday.

Olga Borisova and Sasha Sofeyev were in the Crimea to protest the actions of Russian and Russian backed authorities in the region and had been harassed by security forces for the duration of their visit.

A third member of the band, Marsha Alekhina, remains in Crimea, in detention.
