Fourteen people arrested in Denmark and Germany suspected of planning an attack with explosives had "militant Islamist" motives, Danish intelligence services said Friday. Thirteen people were arrested at the weekend in a suburb outside Copenhagen, Denmark's PET intelligence service said Thursday, confirming another arrest had been made in Germany. "The operation took place due to suspicions that a terror attack motivated by militant Islamism was being prepared," PET said in a statement. The 13 arrested in Denmark were remanded in custody suspected of "planning one or more terrorist attacks or being accessory to attempted terrorism," PET said. They are suspected of "having acquired ingredients and components for manufacturing explosives as well as firearms or having aided and abetted in the offence." Local media reported that the 13 were eight men and five women. Meanwhile, German prosecutors on Thursday said three of the suspects were brothers from Syria, two of whom were arrested in Denmark and one in the German state of Hesse. German police were alerted to the trio last week after they ordered chemicals online that can be used to make explosives. bur-cbw/map/po/spm
