比利时当局正在调查一系列未经授权的无人机飞行事件，这些无人机飞越了包括克莱恩布罗格尔空军基地在内的军事设施，引发了对潜在间谍活动的担忧。
国防部长西奥·弗兰肯证实，周六和周日晚间在比利时东北部的克莱恩布罗格尔空军基地上空检测到了无人机。弗兰肯向公共广播公司RTBF表示，第一阶段涉及“小型无人机测试比利时安全部门的无线电频率”，随后是“大型无人机试图扰乱该地区和人员”。
弗兰肯将这些事件形容为类似间谍行动，但避免对肇事者进行猜测。他排除了恶作剧的可能性，指出操作者在规避无线电干扰器方面展现了技术上的高超能力。
国防部长对法律和后勤限制导致军方无法在民用区域击落无人机表示沮丧，并批评比利时在无人机专用防空系统上的投资迟缓。
近期几周内，类似无人机目击事件也发生在比利时其他军事基地，包括埃尔森博恩和马尔什-昂-法梅讷。
这些事件是欧洲范围内神秘无人机活动的一个更广泛模式的一部分，德国和丹麦近期也报告了类似案例，同时该地区对俄罗斯空域侵犯的担忧持续存在。
