Turkey's deputy prime minister has said his country supports Syria's territorial integrity and will not tolerate the creation of a “de facto'' Syrian Kurdish entity on its borders, AP news agency has reported.

Speaking to reporters on Monday, Bulent Arinc did not spell out what Turkey would do prevent any such entity from coming about, but said it would act carefully and in a cool-headed manner.

Authorities here have been concerned over Syrian Kurdish fighters’ recent strengthening of power in areas bordering Turkey.

The concerns have been heightened by reports that Kurds in Syria are preparing to form an autonomous region in those areas.

Last week, a Syrian Kurdish group affiliated with Turkey's own autonomy-seeking Kurdish rebels took control of a town on the border with Turkey after fighting Al-Nusra Front fighters.
