On Saturday morning it was reported that three people had been arrested at 1:40 a.m. on Saturday on the main road linking Pristina with the town of Gjilan, close to Lake Badovac.
According to local media, the suspects were driving two Volkswagen cars, which were found to contain weapons, ammunition and some materials pertaining to the Islamic State terrorist group.
Later on Saturday, Kosovan prosecutors announced the arrest of two more people on charges of terrorism, in connection with the three earlier arrests.
The National Institute of Public Health also recommended that Kosovo's Regional Water Company "increase its vigilance and protection of water resources" and put in place a strict protective area around the lake.
According to a report published by the Kosovar Center for Security Studies think tank in April, Kosovo contributes the most militants per capita to militant organizations in Syria and Iraq, compared to 21 states in the West from which the Islamic State draws most of its foreign fighters.
Figures up to mid-January 2015 state that 232 Kosovans are confirmed to have joined militant organizations in Syria and Iraq. Per capita, Kosovo has 125 fighters for every million Kosovans.
