Flights have resumed at Germany's Munich airport after unconfirmed drone sightings forced it to suspend operations for the second time in 24 hours.

In a statement on Friday evening, the airport said that flights were stopped at 21:30 local time (20:30 GMT), affecting approximately 6,500 passengers. Earlier, at least 17 flights were grounded on Thursday evening due to similar drone sightings in nearby airspace.

This incident follows a series of drone-related disruptions across European airports and airspaces in recent weeks. On Saturday morning, Munich airport announced that flights were being 'gradually ramped up,' but delays were still anticipated throughout the day, urging passengers to verify flight statuses before departure.

Moreover, authorities in Belgium have been investigating sightings of 15 drones over the Elsenborn military site near the German border, reportedly sighted again in western Germany.

In response to these growing threats, German Interior Minister Alexander Dobrindt is expected to address anti-drone defenses at a forthcoming meeting of European interior ministers. He has indicated intentions to expedite legislation that would permit police to request military support in addressing drone threats.

The recent uptick in drone sightings in Europe prompted a leaders' summit in Copenhagen, during which member states supported plans to establish a 'drone wall' capable of detecting, tracking, and neutralizing threats rapidly. There are increasing suspicions that these incursions may be linked to Russian operators, although the Kremlin has denied involvement.
