The search for many people after the shooting left ten people dead, including children

A gunman killed at least 10 people, including two children, in southern Montenegro and is still at large, police said.

At least some of the deaths occurred at a restaurant in Cetinje area, before the suspect moved to other areas.

A verbal dispute between the guests preceded the shooting, a police officer was quoted as saying by public broadcaster RTCG.

Prime Minister Milojko Spajic described the incident as a “terrible tragedy” and his government declared three days of national mourning from Thursday.

The gunman killed his family members, the two children of the restaurant owner and the landlord, according to Interior Minister Danilo Saranovic.

Mr Saranovic called the incident “the result of a breakdown in interpersonal relations”, according to the AFP news agency.

Four people are in a life-threatening condition in hospital after being seriously injured in a shooting incident, the prime minister said.

The suspect has been arrested for possession of weapons, reports Reuters.

Mass shootings are relatively rare in the small Balkan nation.
