A roadside bomb wounded 15 police officers in a police minibus in Istanbul today, the city's police chief Huseyin Capkin was reported as saying.
The attack happened as the bus was passing a hospital in the Kucukcekmece suburb of Turkey's largest city, state-run Anatolian news agency said.
Istanbul is hosting a regional summit, but the bombing happened more than 20km from the summit location.
"There was an explosion. A bomb was placed by the side of the road and was exploded as the minibus passed. That's the way it looks. It could be a remote control (explosion)," Anatolian quoted Capkin as saying.
"Fifteen of our friends are lightly wounded. We are investigating the incident," he said.
It was not clear who was responsible for the attack.
Kurdish, leftist and Islamist guerrillas have all carried out bombings in the city in the past few years.
