Several people killed in Montenegro shooting: police

The suspect remains at large. 

Police did not specify the number of casualties.

Montenegro's police sent special units to the area and urged people to remain inside their homes.

"All available police units are on the ground, undertaking activities within their jurisdiction," to apprehend the suspect, Montenegro's Police Directorate said in a statement.

Mass shootings are comparatively rare in Montenegro which has a deeply-rooted gun culture.

Despite strict gun laws, the western Balkans remain awash with illegal weapons dating back to World War I.
