"There are people who try to leave but they are also sent back. (…) The Republic of Poland has sent back several dozen of those people who are likely to have crossed the border in Lithuania over the past several weeks," Lithuanian Prime Minister Ingrida Simonyte told the national radio LRT on Friday.
"Obviously, some people have probably managed to reach certain destinations, but definitely not all of them," she added.
Figures provided to BNS by the Interior Ministry show Poland has returned 38 illegal migrants back to Lithuania recently.
Lithuania has seen a spike in illegal migration in recent months as the number of detained illegal migrants has already exceeded the whole last year's figure by almost 20 times. Lithuanian officials say the Minsk regime is behind the recent surge in illegal migrations.
