Brandenburg Interior Minister Karl-Heinz Schröter said Friday that “it is still not clear whether the suspicious package found at a Christmas market in Potsdam included explosives, gypsum or some other «fake material». “There were apparently not only nails but also powder in the canister, and that must be investigated, it could be plaster, or something that doesn´t explode or something... Еще explosive,” said Schröter. “We cannot say, under any circumstance that it contained something able to explode, if it was a fake, or if it was a test. We can only give certain information, and please understand that we cannot give you any more results since we are at the very beginning,” added the Interior Minister. German police evacuated the Christmas market Friday afternoon after the discovery of a suspicious package which was described as measuring 40 by 50 cm (15.7 by 19.7 inches) and delivered to a nearby pharmacy. The incident took place one day before the one-year anniversary of a van attack that took place at Berlin's Breitscheidplatz Christmas market last year, killing 12 people and injuring 48.
