安卡拉致命袭击致死37人后土耳其空袭库尔德工人党

Turkey's military said its warplanes carried out 18 airstrikes Monday targeting Kurdish militants in northern Iraq.

The strikes against the Kurdistan Workers Party, or PKK, came a day after a car bombing killed at least 37 people in Turkey's capital, Ankara.

There has been no claim of responsibility and Turkish officials said they expected to announce the results of the investigation into the blast on Monday.

Turkish forces have been carrying out an offensive against the PKK since July when President Recep Tayyip Erdogan declared the fight would continue until every militant is defeated.

Sunday's blast happened near Kizilay square, a key shopping and transportation hub near foreign embassies and government buildings.

Health Minister Mehmet Muezzinoglu said it targeted civilians at a bus stop, and that more than 120 people were wounded.

Turkish Prime Minister Ahmet Davutoglu convened an emergency security meeting after the bombing.
