The site of the car bombing that hit a police bus in Istanbul on Today. 

 A car bombing that targeted a police vehicle near a central tourist district in Istanbul on Tuesday instantly killed 11 people and wounded dozens more, Turkish officials said.

A parked car was detonated by remote control as a police shuttle bus passed through the historic quarter of the Beyazit district during rush hour, Governor Vasip Sahin of Istanbul said in a televised statement.

Seven of the dead were police officers, Mr. Sahin said, and 36 people were wounded. There was no immediate claim of responsibility for the attack, but Istanbul has been on high alert after two suicide attacks earlier this year that were attributed to the Islamic State.

Kurdish militants from the Kurdistan Workers’ Party, or P.K.K., which has carried out an insurgency against the Turkish state for more than three decades, have claimed responsibility for similar attacks against Turkish security forces since the breakdown last July of a fragile peace process.

A militant group with links to the Kurdish group claimed two major attacks in the capital, Ankara, earlier this year that struck a military convoy and civilians, killing dozens of people.
