A gunman has gone on a rampage killing 10 people before he was shot dead by a passer-by.
Eleven people, including two children and the attacker, were killed in a mass shooting in Montenegro on Friday, and six others were injured, a state prosecutor has confirmed.
Montenegro Police director Zoran Brdjanin said that around 3.30pm local time (2.30pm BST) a 34-year old man with a hunting rifle when on a rampage.
He shot dead two siblings, one 8 years old and another 11 years old, and injured their mother who died later in the afternoon in a medical facility.
"The family was staying at the house of the shooter as tenants," Brdjanin said.
He said the motive for the shooting was not yet known, and he did not give the name of the shooter but said his initials were V.B.
The shooter then walked out of his house and killed another seven people.
In a shootout with the police, a policeman was injured, Brdjanin said.
"When we arrived at the scene we saw nine dead bodies, including two children, and another two passed away on their way to the hospital," Andrijana Nastic, a state prosecutor, told Vijesti TV.
She added: "For now, it is not clear what prompted [the suspect] to commit such a heinous act, on which occasion he himself was deprived of his life."
Earlier, media reported that police had killed the shooter but it was later confirmed to be a passer-by who subdued him.
Montenegro's Prime Minister Dritan Abazovic said a three-day mourning period would be declared in the country starting Friday evening.
He wrote on his Telegram channel that the incident was "an unprecedented tragedy" and urged people "to be, in their thoughts, with the families of the innocent victims, their relatives, friends and all the people of Cetinje".
"I was deeply disturbed with reports about terrible tragedy in Cetinje. I express my deepest condolences to those families affected and all those who lost their loved ones," President Milo Djukanovic tweeted.
Cetinje, the seat of Montenegro's former royal government, is 22 miles west of Podgorica, the current capital of the small Balkan nation.
