Montenegro mourns after gunman kills at least 12 people before ...

Shock and dismay prevailed in Montenegro on Thursday after a gunman fatally shot 12 people, including two children, in a western town before killing himself.

At least four others were wounded in the shooting rampage in Cetinje on Wednesday that followed a bar brawl, officials said.

This was the second such incident in the town in the past three years.

The shooter, identified as 45-year-old Aco Martinović, killed the owner of the bar, the bar owner's children and his own family members, officials have said.

The attacker, who first fled after the rampage, was later located and surrounded by police. He died after shooting himself in the head, Interior Minister Danilo Šaranović said.

Residents of Cetinje, a town of some 17,000 people, were stunned and grief-stricken.

"I knew all of these people personally, also the attacker. I think when he did that, he was out of his mind," said Vesko Milošević, a retiree from Cetnje.

"What do I know, he went from place to place and killed people. Its a catastrophe."

Vanja Popović, whose relatives are among the victims, said that "we are all in shock."

"How can I feel after this?" Popović said. "No one expected it. You can't even ask anyone anything."

Police had dispatched a special unit to search for the attacker in the town, which is located about 30 kilometres northwest of Podgorica, the capital. All roads in and out of the city were blocked for hours as police swarmed the streets.

Šaranović said that the shooter had died while being taken to a hospital in the capital and succumbed from the "severity of his injuries."

Officials have said that the attacker was at the bar throughout the day with other guests when the brawl erupted. He then went home, brought back a weapon and opened fire at around 5.30pm.

Prosecutor Andrijana Nastić said on Thursday that the attacker went to six locations during the shooting rampage, including the last one, where he shot himself.

Four men were killed at the bar, Nastić said. The shooter then moved on to another location where he killed four more people, and then two children at a third site. He then went on to kill two more people at two other locations before eventually shooting himself, Nastić said.

"Further investigation will determine the exact circumstances of the events," she added.

The government has declared three days of national mourning starting on Thursday, and all planned New Year's festivities have been cancelled throughout the country.

Prime Minister Milojko Spajić said that the government may try to impose a total ban on weapons "because we must ask ourselves after this who should be allowed to have guns in Montenegro."

The small Adriatic Sea nation, which has a population of around 620,000 people, is known for its gun culture and many people traditionally have weapons.

In August 2022 in Cetinje, which is Montenegro's historic capital, an attacker killed 10 people, including two children, before he was shot and killed by a passerby.

Police have said that the suspect in Wednesday's shooting received a suspended sentence in 2005 for violent behaviour and had appealled his latest conviction for illegal weapons possession. Montenegrin media have reported that he was known for erratic and violent behaviour.

"Instead of holiday joy ... we have been gripped by sadness over the loss of innocent lives," Montenegro's President Jakov Milatović said in a post on X.
