A New Zealand reporter has ended up in hospital with concussion after being beaten up in Kyiv, news website Telekritika said on Saturday, citing the Facebook page of a Ukrainian journalist.

Jared Morgan was assaulted next to the building in Kyiv where he lives by men who "disliked his pro-Ukrainian views," Andre Alexin said on Facebook, citing Morgan as saying the attackers had been three men who might be refugees from eastern Ukraine.

Telekritika said Morgan has been living in Kyiv since 2011, and that he is a former reporter for Australia's Fairfax Media company and the winner of a prize from New Zealand's Kiwi Journalists Association.

The Ukrainian Interior Ministry said police had taken up the case.

However, Kyiv's police force "has received no statement from [Morgan], nor have there been any reports about this incident from medical institutions," the ministry said in a statement.
