Namibia package was security test
A suspicious package found in a Namibian airport near bags bound for Munich was designed to test airport security, Germany's top security official has said.
But officials are still trying to determine who carried out the test.
Thomas de Maiziere said German experts sent to Windhoek airport after the incident on Wednesday had inspected the bag and determined it was a case made by an American firm to test airport security measures. He did not say who may have left the case in the luggage hall, adding that German agents were still investigating.
The threat came amid heightened concerns of terrorist threats against Germany that prompted Mr de Maiziere to raise the country's threat level even before the Windhoek incident.
"Most important is that there were no explosives in the bag and there was never any danger to the passengers at any time," the Interior Minister said.
When asked if it could have been a German security test, Mr de Maiziere said that was "unlikely but part of the investigation".
Concern about the possibility of international flights being targeted by terrorists rose last month when two mail bombs were discovered being sent on cargo planes from Yemen to the US. One of them went through a German airport before being found in Britain.
The Windhoek incident came as Germany was on edge after Mr de Maiziere raised the country's terrorist threat level, saying intelligence services had received a tip from an unspecified country about a suspected attack planned for the end of November.
In comments published in Germany's Bild newspaper, Germany's federal police president said the terrorist threat facing the nation was "more serious than ever before".
While urging against "panic or hysteria," Matthias Seeger said that "on a scale of one - no danger, to 10 - acute danger of an attack - we are currently at 9. Therefore we need to be particularly alert".
