Police in Istanbul conducted a series raids in the city targeting Islamic State suspects, the state-run news agency reported Thursday, following the gunfire and suicide bomb attack at Ataturk Airport which killed 42 people.

It was an attack that echoed the carnage earlier this year at the Brussels airport, down to the taxi that carried the men to their target.

The carnage in Turkey is the latest in a string of attacks that underline the increasing threat of terrorism in a country once known for its stable tourism industry.
