Six people were killed and another 14 were injured on Saturday after a man opened fire on the streets of the Ukrainian capital, according to media reports.

Earlier in the day, a gunman opened fire on pedestrians in Kyiv's southern Holosiivsky district. Following the shooting, the attacker took people hostage in a nearby supermarket, Interior Minister Ihor Klymenko said.

He added that the attacker was killed during the arrest.

Ukraine's Prosecutor General's Office said the attacker was a 58-year-old man.

The Security Service of Ukraine (SSU) said Saturday that it is considering the shooting in Kyiv as a terrorist act, the Interfax-Ukraine news agency reported.

"Investigators of the Security Service of Ukraine have classified the shooting of civilians and the taking of hostages in the Holosiivsky district of Kyiv as a terrorist act," the SSU said in a statement.

The motives behind the incident are being investigated.
