Istanbul Governor Muammer Guler told Turkish television two people were killed, including a police officer and a bystander, and seven heavily armed police officers were wounded in the Monday shooting, the newspaper Today's Zaman reported.
Guler said the deadly raid was one of more than 60 assaults conducted in Istanbul overnight Monday, targeting militants suspected of planning what he called "sensational attacks."
"These are extreme leftist, separatist and radical groups," Guler reportedly said. "There are more than 10 detained in the operations. Terrorists responded by throwing bombs in some places and seven policemen were wounded."
