ISTANBUL—Turkey said it carried out a broad series of airstrikes in northern Syria and Iraq early on Sunday, intensifying a military campaign against Kurdish militants, whom the Turkish government blames for a deadly bombing in Istanbul a week ago.
The Turkish Defense Ministry said the strikes hit 89 separate targets associated with the Kurdistan Workers’ Party and its Syrian branch, which Turkey blamed for a bombing in Istanbul last week that killed six people and wounded 81 others. The PKK—as the Kurdish group is known—and its Syrian branch both denied involvement in the attack, and no one has claimed responsibility.
