Operations at Belgium's Brussels Airport were temporarily halted on Thursday due to a drone sighting, a spokesperson for air traffic control Skeyes said on Thursday, without specifying how many drones had been seen.
Local media reported drones had been sighted in other parts of the country as well, among others at a military base.
The Belgian government had called an emergency meeting of key government ministers and security chiefs earlier on Thursday morning after drone sightings forced closures of airports and a military air base on Tuesday evening in what the defense minister called a coordinated attack.
Germany has said the Bundeswehr will provide Belgium with short-notice support in counter–drone capabilities.
Drones have caused major disruptions across Europe in recent months, forcing temporary closures of airports in several countries. Some officials have blamed the incidents on "hybrid warfare" by Russia. Moscow has denied any connection with the incidents.

One or more drones were observed at the Gothenburg-Landvetter Airport on Sweden's west coast around 5:41 p.m., authorities said earlier on Thursday, forcing more than a dozen flights to be rerouted or canceled.
"A drone or drones have been observed at Landvetter Airport," a spokesperson at civil aviation agency LFV said.
A police spokesperson said police received a report of suspected drone sightings by several individuals at 5:41 p.m. and were at the scene gathering information, trying to confirm the report.
"We have launched an investigation into suspected aviation sabotage," the police spokesperson said.
Airspace above airport
The airport is Sweden's second-biggest after Stockholm's Arlanda, according to airport operator Swedavia.
"The airspace above Landvetter is currently closed due to indications of a suspected drone," Swedavia Chief Operating Officer Susanne Norman said. "The airspace will remain closed while the police investigate."
On Tuesday, drone sightings forced closures of airports and a military air base in Belgium in what the country's defense minister called a coordinated attack.
On Thursday, police in Sweden's neighbor Norway said they had closed a probe into suspected sightings that caused a shutdown of Oslo's airport in September, citing insufficient evidence that drones had been present.
In neighboring Denmark, several airports, including Copenhagen, also closed temporarily in September due to reported drone sightings.
