The explosions in stores in the Belgian city of Ghent, Lille in northern France and Eindhoven in The Netherlands caused no damage or injuries.
"The information we have is that the explosions happened the same way in all locations, with booby-trapped alarm clocks that had been hidden exploding," An Schoonjans, spokeswoman for Ghent prosecutors, told AFP.
In Ghent, an employee and a security agent complained of ear aches after two small explosions, which detonated almost simultaneously before the store closed Monday evening.
Two booby-trapped alarm clocks were detonated by remote control, Schoonjans said.
