The Turkish army and US-led coalition forces are reported to have attacked Islamic State (IS) targets in northern Syria, killing 27 militants.
Military sources quoted in Turkish state-run media said the air and artillery strikes took place on Sunday within 10km (six miles) of the border.
They said the militants were killed as they prepared to fire rockets.
On Monday, Turkey reportedly detained seven suspected IS members including one described as an IS "executioner".
The suspects were held in raids in the Elazig area of eastern Turkey, state-run Anatolia news agency reported.
