An explosion went off Friday at a police checkpoint in the southern Turkish town of Suruc close to the Syrian border causing injuries, reports said.

The cause of the blast was not clear but Turkish media said emergency service vehicles rushed to the scene, reports AFP.

NTV television said at least one policeman was wounded in the blast.

Suruc lies just over the border from the Syrian town of Kobane which was recaptured last month by Kurdish fighters after a battle with Islamic State (ISIS) jihadists.

Reportedly 3,000 people in Turkey are linked to ISIS, with there being a fear in the country that the large number of jihadists may turn their sights on local targets.

Turkey has been a key entry point for jihadists flocking to join ISIS in Syria.

The country has been accused of not doing enough to stem that tide of migrant jihadists, and in a recent report one ISIS recruit from the UK said Turkish police showed ISIS members sympathy and even bought them pizza while they were jailed there.
