A protest held in Skopje over last week's killings of five male Macedonians left five people wounded and about ten detained.

Two police officers are among the wounded. Around 1,000 enraged people took part in the protest late Monday, says an Interior Ministry's statement.

The demonstrators gathered in front of the government building without prior notice, shouting out slogans and throwing stones at the building. The riots left several windows broken and one police car damaged. Three passers-by reported minor injuries inflicted by unknown perpetrators.

The police stated that informative talks with around ten detained persons are underway, after which criminal charges will be filed.

Four men aged between 18 and 20 were killed in Radisani, near Skopje on Thursday evening. Their bodies were found near an artificial lake, together with a body of a 45-year-old man. They all had gunshot wounds.

Certain web portals have speculated about possible motives, one being retaliation for the recent murder of two ethnic Albanian youths in Gostivar, killed by a police officer who was attacked while taking his underage daughter home.
