For the second time this week, Belgium's Liege airport has been forced to temporarily halt operations due to suspicious drone sightings. The incident was confirmed by the Belga news agency, citing aviation service skeyes.

In Belgium, incidents of drones over sensitive areas are becoming more frequent, and this is not an isolated problem - other countries, including Sweden, are also reporting disturbances. Some officials are openly talking about a possible form of hybrid warfare by Russia, although Moscow denies the allegations.

The Belgian government has already called an emergency security meeting where the defence minister said there was talk of a coordinated attack.
