NERIS SUBSTATION, Lithuania (Reuters) -Four NATO and European Union countries bordering Russia plan to build concrete bunkers and anti-drone nets at vital energy facilities under a plan to protect their power grids following Russian drone incursions.
Violations of Polish airspace by Russian drones this month and multiple drone sightings, including one that forced the closure of Copenhagen Airport for several hours, have raised concerns about NATO's defences on its eastern flank.
