Ljubljana - Long tailbacks of traffic have built up at crossings on the Slovenian-Croatian border as holidaymakers from northern Europe hit Croatian coastal resorts.

Data by the national traffic information centre for Saturday midday shows waiting times of more than two hours at all major crossings for vehicles entering Croatia.

The situation is currently worst at small border crossings such as Vinica, where those entering Croatia can expect to wait for up to six hours.

At major crossings such as Obrežje/Bregana, Gruškovje/Macelj and Jelšane/Rupa, the waiting times are between two and four hours.

Traffic in the opposite direction has gotten just as bad. Most crossings report waiting times of more than two hours to enter Slovenia, but on coastal crossings waiting times of up to four hours are currently expected.

The situation on the border with Austria has deteriorated as well. At the biggest crossing, Karavanke, there is currently a four-kilometre tailback.
