(AP) Cologne police acting on indications of a possible attack searched Germany’s landmark cathedral with sniffer dogs Saturday and said worshippers attending Christmas Eve Mass would undergo security screening before being allowed in.
In Austria, police in Vienna also said they were taking heightened security measures around churches and Christmas markets, deploying both uniformed and plainclothes officers.
Neither police agency specified the threat, but the German news agency dpa said authorities were responding to signs of a possible attack by Islamic extremists, without citing a specific source.
