Turkish media reports say an explosion has rocked a major city in northwestern Turkey.

The private Dogan News agency says the explosion hit near the Grand Mosque of Bursa and broadcast footage shows people fleeing the area.

NTV television says three people were wounded by the blast. The state-run Anadolu Agency says ambulances and fire brigades have been deployed to the scene.

There was no immediate word on the cause of the explosion.

Turkey has recently been hit by several attacks by the Islamic State group and Kurdish rebels but also on occasion witnesses explosions related to natural gas malfunctions.

The United States on Tuesday issued a new warning to its citizens about "credible indications" of terrorist threats at tourist areas in Turkey.
