Backpacking Istanbul Metropolitan Municipality with a story

A car bomb ripped through a police bus in central Istanbul during the morning rush hour on Tuesday, killing 11 people and wounding 36 near the main tourist district, a major university and the mayor's office.
The car was detonated as police buses passed, Istanbul Governor Vasip Sahin told reporters, in the fourth major bombing in Turkey's biggest city this year.
There was no immediate claim of responsibility but Kurdish militants have staged similar attacks on the security forces before, including one last month in Istanbul.
