ANKARA: At least 30 civilians were killed and many others were wounded on Sunday after ISIS launched an attack in the Syrian town of al-Bab to prevent people from fleeing, the Turkish military said in a statement on Monday.

Syrian rebels supported by Turkish troops have laid siege to the ISIS-held town for weeks under the "Euphrates Shield" operation launched by Turkey nearly four months ago to sweep the Sunni hardliners and Kurdish fighters from its Syrian border.
