CCTV footage has emerged of the moment armed men seized the Crimea parliament building in Simferopol, Ukraine.
The images show the group - wearing unmarked military uniforms - outside the building, before entering amid an explosion in the early hours of Thursday.
On Friday, Ukraine's acting president accused Russia of deploying troops there to provoke an "armed conflict", which Moscow denies.
