A bomb exploded in one of the Turkish capital's busiest commercial centers, killing six people and injuring 100, authorities said Wednesday. The blast Tuesday outside one of the oldest shopping malls in Ankara hurled glass and other debris over a wide area. A body, covered in a white sheet, lay outside the building. Prime Minister Recep Tayyip Erdogan said four Turks and one Pakistani were killed in the blast. Police said an injured person died later in a hospital, raising the death toll to six. «Is it a suicide bomber or a parcel bomb? Technical teams are working on this,» Erdogan told reporters after visiting the scene. «We have always said terror can strike anyone, anywhere. Although we have taken every precaution, we have experienced this incident.» The governor's office said, however, that 10 Pakistanis were among 100 injured, and that 16 were in critical condition, according to a report of the Associated Press.
