The parked car exploded in a road in Istanbul's Sancaktepe neighborhood as a bus carrying military personnel passed by, the army said in a statement. The civilian driver was among the injured, it said, Reuters wrote.
The blast sent a large plume of smoke up over Sancaktepe, which is near a military airfield on the Asian side of the city, well removed from Istanbul's historic center.
"Our citizens are being treated at the hospital. Seven people have light injuries due to shattered glass, six of them soldiers, one civilian," Sancaktepe Mayor Ismail Erdem told CNN Turk.
The car exploded at around 5 p.m. (1400 GMT), a time when military personnel usually leave the nearby base to go home, according to the broadcaster.
