North Macedonia police probe water supply after mass poisoning

Although the hospital in the town of Gostivar -- about 50 kilometres (30 miles) southwest of the capital Skopje -- did not confirm a direct cause, it said it had treated a large number of people with vomiting, diarrhoea and stomach pain over the past four days.

Police were investigating the cause but believed the local water company may have pumped wastewater directly into the town's water supply.

The local force said in a statement the idea was most likely to increase the supply of drinking water -- the area regularly suffers from shortages during the summer.

Authorities have temporarily banned drinking from the town's supply, and the hospital has boosted staff to manage the influx of sick people.

The interior ministry said it was working to "fully clarify the case" and that polluting drinking water could be considered a crime.

The public health institute has begun testing the water supply, with results expected within 48 hours.
