Russian President Vladimir Putin has demanded an apology from the Netherlands over what Moscow says was an unprovoked attack on a Russian diplomat by unidentified assailants.
According to the Russian Foreign Ministry, attackers "wearing something like police uniforms" entered an apartment belonging to embassy diplomat Dmitry Borodin.
They reportedly beat him with a baton before escorting him to a police station.
Russia has lodged a formal diplomatic protest over the incident and the Dutch ambassador has been summoned to provide an "exhaustive explanation".
It comes at tense moment in relations between Russia and the Netherlands, which are at odds over the prosecution of environmental activists involved in a protest in the Arctic.
