VILNIUS: A first team of six guards from the EU border agency Frontex began working in Lithuania on Friday, as the Baltic state reported another sharp rise in migrants arriving from Belarus. The Lithuanian border guard service said that over the last 24 hours alone they had detained 150 migrants -- almost twice as many as for the whole of 2020. That brings the total number of detected illegal crossings by migrants, most of them from the Middle East, to more than 800 so far this year.
