At least 45 Kurdish rebels have been killed in air strikes on northern Iraq following the suicide car bombing in Ankara, Turkey's military has said.

Turkish F-16 and F4 jets raided Kurdistan Workers Party, or PKK, positions across the border in Iraq on Monday, a day after the attack which killed 37 people.

Turkish Prime Minister Ahmet Davutoglu said authorities are "almost certain" that Sunday's bombing was the work of the PKK.

A military statement on Tuesday 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.
