The number is up from 73 on Monday.

"We see movement of those groups. Not all of them that have approached today are making attempts to cross as there have been also people who retreated," he said.

In his words, migrants are gathering close to the intersection of the Belarusian, Polish and Lithuanian border. The situation is more tense than before but no major unrest incidents have been recorded, Misutis said.

Lithuanian border guards have foiled a total number of 6,017 attempts to illegally cross the Lithuanian-Belarusian border since early August when the Lithuanian government allowed border guards to turn such migrants back to Belarus.

Lithuania redeployed border guard forces after a large column of illegal migrants moved towards the Polish border and tried to storm its way through. Some 1,000-2,000 illegal migrants were reported to have gathered there on Monday.
