A car bomb that ripped through a police bus in central Istanbul on Tuesday, killing 11 people and wounding 36, was the latest in a string of deadly attacks throughout Turkey over the past year.
The attack was the fourth since January in the cosmopolitan city of 14 million, which until this year has been largely isolated from the turmoil of civil wars in neighboring Syria and Iraq.
The attacks are eroding a sense of normality among many Turks, and security concerns are already hurting tourism and investor confidence.
“Everyone feels a bit tense,” said Tobias Wilms, a 25-year-old German who has been working in Istanbul for the past six months. “You see it and feel it in the buses, the streetcars and the underground.”
But Mr. Wilms, whose workplace is near the site of Tuesday’s bombing, spoke of an “emotional tolerance” to the terrorist attacks. “People at work didn’t even talk about it,” he told Handelsblatt Global Edition. “It’s as if they want to ignore these incidents – to keep their peace of mind.”
