"Movement near the state border is ongoing. Even being here, our officers hear the sounds of heavy machinery in the Belarusian territory, which might mean that trucks are possibly bringing in illegal migrants," he told journalists at the Kapciamiestis Frontier Station on Wednesday.

"The fact is that representatives of Belarusian law enforcement institutions are really taking illegal migrants and then pushed into Lithuania's territory," he added.

His comments came as a state of emergency came into force in Lithuania on midnight in response to a new influx of illegal migrants.
