Lithuania's Vilnius airport temporarily closed on Thursday due to weather balloons flying in its vicinity, the airport said in a post on Facebook, the sixth such incident this month.

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

Lithuania’s two border crossings with Belarus, at Medininkai and Šalčininkai, were losed for several hours as a result of each of the balloon incidents before being reopened.

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,
