The runway at Munich airport in Germany was temporarily closed on Saturday evening due to reports of "suspicious" activities, DPA reported, quoted by BTA.
Air traffic control stopped air traffic at Munich airport for half an hour at around 10:00 p.m. local time (11:00 p.m. Bulgarian time), a police spokesman told DPA.
Another short closure of the runway followed an hour later.
Earlier, several people reported to police officers that they had seen something "suspicious", but it was not clear whether they were drones.
According to information on the airport website, two flights were diverted during the closures.
In early October, air traffic at the airport in the Bavarian capital was suspended for two consecutive evenings due to unregulated drone incursions.
Almost 10 000 passengers were affected by the traffic disruption at the airport.
Similar incidents have affected the operation of other European airports in recent weeks.
A majority of Germans are against the idea of selecting citizens by lottery to be obliged to perform military service in the German armed forces. This is according to the conclusions of a survey by the INSA public opinion research institute, prepared for the German newspaper "Bild", DPA reported.
The government of Chancellor Friedrich Merz intends to restore some form of military conscription in Germany, which was abolished in 2011, in order to respond to the growing threat from Russia and to strengthen the Bundeswehr in line with NATO's new defense goals.
According to the survey, 60 percent of respondents believe that it is wrong to use a lottery system to determine who should serve in the army.
Only about a fifth of those surveyed believe that it is right to use such a system.
Defense Minister Boris Pistorius told "Bild" that the decision on how to expand the ranks of the army is already in the hands of parliament.
He defended voluntary military service, saying it should remain as long as possible.
The ruling coalition in Berlin is divided on the issue of compulsory military service. The Social Democrats, of which Pistorius is a member, insist that the new military service should be voluntary, while Merz's Christian Democratic Union (CDU) and the CDU's sister party, the Bavarian Christian Social Union (CSU), support the introduction of a mandatory element.
Because of this division, the first reading of a bill on a new military service organization in the lower house of the German parliament (Bundestag) was postponed last week, and a press conference on Tuesday at which a deal between the coalition partners was expected to be announced was canceled at the last minute.
