Turkish warplanes bombed Kurdish rebel targets in northern Iraq on Wednesday, a Kurdish news agency reported. The Firat news agency said jets hit the Hakurk region of northern Iraq for 45 minutes. The area is where the borders of Iraq, Turkey and Iran meet and where the rebels of the Kurdistan Workers' Party maintain a major camp. Firat, quoting Kurdish party officials, said the rebels "responded" to the airstrikes, but gave no details. There were no casualties, the agency said. Earlier, Turkey's private Dogan news agency, quoting Iraqi Kurds, said four Turkish warplanes were involved in the attack. Turkey's military did not immediately confirm the report.
