Turkey's military, backing Syrian rebels in a four-month-old operation against Islamic State militants in northern Syria, said on Tuesday that 18 of the jihadists had been killed and 37 wounded in clashes and artillery fire on Monday.
In a round-up of its operations over the past 24 hours, the army said its warplanes destroyed four Islamic State targets and Russian aircraft hit jihadists in Dayr Kak, 8 km (5 miles) southwest of the Islamic State-controlled town of al-Bab.
