Officials say Serbia's ambassador to NATO committed suicide by leaping from a busy parking garage platform at Brussels Airport.
A Serbian government statement said on Wednesday that the envoy, Branislav Milinkovic, 52, died instantly on Tuesday night.
A diplomat who could not be identified because he was not authorised to speak to the media said Milinkovic suddenly jumped from the 8- to 10-meter-high (26- to 33-foot-high) platform while waiting with the Serbian delegation for foreign ministry officials due to hold talks with NATO officials.
Serbia is not a member of the military alliance, but has a mission in the headquarters complex. Milinkovic, a former journalist, previously served as Serbia's ambassador to Austria.
The death occurred during two days of meetings of NATO foreign ministers in Brussels.
