An unidentified assailant has fired a rocket-propelled grenade at a Ukrainian television station in the capital of Kiev.

No one was hurt in the attack on Saturday, and Kiev police have initiated a search for suspects.

Authorities have classified the attack as an act of terrorism.

The target was the Ukraine 112 television station, a network considered by some to be pro-Russian.

On Thursday, Ukraine's prosecutor general threatened legal action if the network airs a new Oliver Stone documentary that features an interview with Russia's president Vladimir Putin.

Ukraine 112, a 24-hour news network, is owned Taras Kozak, who is running for parliament for the Opposition Bloc Party, organised by Viktor Medvedchuk.

Mr Medvedchuk has ties to Mr Putin and was sanctioned by the US in 2014.
