Turkish F-16 and F4 jets raided Kurdistan Workers Party, or PKK, positions across the border in Iraq yesterday, a day after the attack which killed 37 people. Turkish Prime Minister Ahmet Davutoglu says authorities are "almost certain" that the attack was the work of the PKK.

A military statement today said the air strikes killed 45 PKK rebels and destroyed two arms depots and two rocket launcher positions.

The military claim could not immediately be verified.
