False alarm leads to US consulate evacuation in Berlin Workers have returned to the US consulate building in Berlin after a false alarm was triggered by a suspect package. Earlier, staff were evacuated after an employee experienced breathing difficulties when opening a hand-delivered envelope that was supposed to contain visa application documents. Following an investigation by German and US authorities, including a probe for hazardous material, the situation was deemed safe. It is believed the man who dropped off the envelope was an Albanian national applying for a US visa. US embassies are on high-alert following violence in Libya, where four diplomats were killed on Tuesday night, and protests at embassies in Egypt and Yemen. More about: Germany, USA
