Austria strengthened coronavirus controls on its border with Slovenia on the weekend, causing traffic chaos and angering Slovenian police until they relented on Sunday.
From Saturday until noon on Sunday, Austria stopped every car entering from Slovenia to record personal data from all passengers to help track infections after a spike in cases, Austrian police said.
Long stretches of cars were backed up from the Karawanks and Loibl tunnels, busy crossing points between northern and southern Europe.
