Police say a bomb has exploded at a shopping mall in the Greek capital of Athens, slightly wounding two security guards. Police say two warning phone calls were made to local media about 50 minutes before the blast on Sunday, and police evacuated about 200 people from the mall, located in the Maroussi suburb north of the city center. Shops are closed at the mall on Sundays, but cafeteria, restaurants and movie theaters in the complex are open, according to a report of the Associated Press.
