A gunman has killed 10 people, including two children and their mother, before being shot dead by a civilian in the western Montenegro city of Cetinje.
Six others were injured, a state prosecutor told the country's national television station Vijesti TV after an initial investigation of the crime scene.
Montenegro Police Director Zoran Brdjanin said Friday that about 3: 30 pm a 34-year old man with a hunting rifle shot dead two siblings, one 8 years old and another 11, and injured his mother, who died later in a medical facility.
The family was staying at the house of the shooter as tenants, Mr 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 VB.
After shooting the children and their mother, the shooter walked out of his house and killed another seven people.
An officer was injured during a shoot-out with the police, Mr Brdjanin said.
When we arrived at the scene, nine bodies, including two children, were found dead and another two passed away on their way to the hospital, Andrijana Nastic, a state prosecutor, told Vijesti TV.
The media reported that the police had killed the shooter.
Montenegro's prime minister Dritan Abazovic said a three-day mourning period would be declared in the country starting Friday evening.
President Milo Djukanovic said that he was deeply disturbed by reports about the terrible tragedy in Cetinje. I have to express my deepest condolences to the families affected and all those who lost their loved ones.
