By Andrius Sytas VILNIUS (Reuters) -Border crossings between Lithuania and Belarus will remain closed for most travellers until the end of November in response to recent airspace disruptions by smugglers' balloons,

Lithuania accuses Belarus and Russia of a "deliberate escalation of hybrid warfare" as balloons shut down major airport.

Lithuania’s recent experimentation comes shortly after the country adopted a law granting its military the authority to shoot down hostile drones in its airspace.

For the third night in a row, Lithuania, one of NATO’s front-line member states, was forced to close its main airports after strange balloon from Belarus entered its airspace. Officials confirmed that Vilnius Airport had to suspend operations late Sunday night,

Russian jets violated NATO airspace over Lithuania for 18 seconds during suspected refueling exercise. Nation's president calls it a breach of international law amid tensions.
