ATHENS, Jan. 20 (Xinhua) -- An explosive device went off on Sunday noon at a major shopping mall in the northern suburbs of Athens, causing the slight injuries of two security guards, local media reported.
The bomb had been placed on the building's first floor near a bank branch, according to police sources. The two men have been transferred to a nearby hospital with minor injuries from shattered glass.
Shortly before the explosion there had been a warning phone call at a Greek daily to evacuate the building. According to unconfirmed reports the perpetrators misled police, indicating that the device had been hidden at the garage.
As a counter-terrorism squad is searching for clues, police has cordoned off the area which is flocked with thousands people during weekdays and Saturdays.
On Sundays, only cafeterias, restaurants and cinemas are open at the popular shopping center and it is estimated that there had been approximately 200 people inside before the explosion.
