ANKARA: Syrian opposition fighters backed by Turkish warplanes killed 68 Daesh militants in northern Syria overnight, the Turkish military said on Saturday, as intense fighting around the town of Al-Bab continued.

Opposition fighters supported by Turkish troops have laid siege to the Daesh-held town for weeks under the “Euphrates Shield” operation launched by Turkey nearly four months ago to sweep the hard-liners and Kurdish fighters from its Syrian border.

Fighting around Al-Bab has escalated this week with Turkish soldiers and 138 terrorists killed in clashes on Wednesday in the deadliest day since the start of Turkey’s Syrian incursion.

Sixty-eight Daesh militants have been “neutralized” in fighting and airstrikes near Al-Bab since Friday night, the military said in a statement.

A total of 141 Daesh targets were hit in the attacks and one of its military headquarters was destroyed, the military said, adding that two of the Turkish-backed fighters had been killed and one wounded.

Defense Minister Fikri Isik said on Friday that the area around a hospital used as a command center and ammunition depot by Daesh had been cleared of militants, marking a breakthrough for the fighters.

Speaking in Kocaeli province, near Istanbul, Isik also said authorities had information three Turkish soldiers had been captured by Daesh but nothing else had been confirmed.
