One of the team of European monitors seized by pro-Russian separatists in the eastern Ukrainian flashpoint city of Sloviansk on Friday has been freed.

The man, reportedly Swedish, was released on medical grounds, a separatist spokeswoman told the BBC.

The eight monitors - linked to the Vienna-based Organization for Security and Co-operation in Europe - were shown to the media on Sunday.

Intensive diplomacy has been going on to try to secure their freedom.
