The U.S. and Turkey are discussing plans to clear ISIL from a zone along the Turkish-Syrian border. Meanwhile in eastern Turkey, two policemen have died and dozens more were wounded in a suicide attack Sunday. The army said the attack was carried out by members of the Kurdistan Workers’ Party, known as the PKK. The army also accused the PKK of killing one soldier on patrol in eastern Turkey in a separate attack Saturday. These attacks come after Turkey has launched a wave of airstrikes against PKK camps in northern Iraq over the last two weeks.
