German suitcase bombs 'part of terrorist plot'

CNN reports.

WIESBADEN, Germany (CNN) -- German officials said on Friday that suitcase bombs that failed to go off on two regional trains July 31 were likely part of a failed terrorist attack and released surveillance video of possible suspects they are seeking.

"If these bombs were detonated, this very likely would have caused deaths and injured," German Interior Minister Wolfgang Schaeuble said.

"Therefore we have to take this event very seriously. And we have to expect that the danger of a repeat attempt still exists. And therefore the public manhunt for these persons is necessary." [...]

The suitcases were identical black cases with a gas canister, alarm clock, wires, batteries and soft drink bottles filled with flammable liquid.
