'We do not have many details at the moment. The only thing we can say is that we have quite a big situation. Part of the tribune has collapsed, so we have some people beneath it and we have got some people [police officers] there at the moment,' a spokesperson said. 'We can't say any more about what is going on because we have had no contact from our people from our station who are there at the moment' Photograph: Martin Meissner/AP
