Turkish forces have killed 200 Islamic State militants in Syria and Iraq, Turkish Prime Minister Ahmet Davutoglu has announced. The retaliation responds to a suicide bomb attack that killed 10 German travelers in Istanbul this week. Fifteen people were hurt in the bombing, including Germans. The New York Times newspaper reports citizens of Norway, Peru and South Korea were also wounded. Davutoglu said Turkish forces attacked numerous Islamic State terrorist group targets along its border with Syria and near a Turkish camp in northern Iraq. They used artillery and tanks in the attacks, which were carried out within the past two days. He said if necessary, Turkey would also launch air attacks against the group. And he said Turkish forces will pressure the Islamist fighters until they leave the border areas. However, Turkey’s war planes have not flown in Syrian air space since late November, when a Turkish pilot shot down a Russian fighter jet.
