VIENNA, Aug. 9 (Xinhua) -- Austria is to tighten its border controls on the back of an increase in illegal migration in recent days, interior minister Wolfgang Sobotka confirmed on Wednesday.

The Krone newspaper reported that the authorities had come across numerous large groups of migrants attempting to cross into Austria.

It was also noted that new migration routes into the country had been observed.

As a result, Sobotka ordered the establishment of temporary control checkpoints by the police, with armed forces personnel to offer assistance.

The controls, including car inspections, are to be in place on the shared border with Slovakia, Hungary, Slovenia, and Italy.
