At least 10 people were killed in a mass shooting on Wednesday in the tiny Balkan country of Montenegro.

Reuters and other media say a man opened fire on Wednesday afternoon at a restaurant in a small town in the west of the country.

The man then moved on to three other locations and continued his shooting rampage. The dead included the owner of a bar and the owner's two children. Four people were seriously injured.

The 45-year-old attacker, who had fled the scene, attempted suicide near his home after being cornered by police. He was later confirmed dead.

The motives and other details have not been made clear. But police say the suspect was thought to have been drinking heavily and there had been a brawl before shots were fired.

Wednesday's incident was the second shooting rampage over the past three years in Montenegro. An attacker also killed 10 people, including two children, in 2022 before he was shot and killed by a passerby.

Montenegrin Prime Minister Milojko Spajic said authorities would consider tightening criteria for owning and carrying firearms.

President Jakov Milatovic said on social media that he was "shocked and stunned" and is "gripped by sadness over the loss of innocent lives."
