Two of the injured were in serious condition, said the report, adding an investigation into the blast was underway, Anatolia news agency reported.

Earlier on Saturday, a bomb planted by the outlawed Kurdish Workers' Party (PKK) on a railway track in eastern Turkey was detonated remotely, derailing seven carriages of a freight train and damaging a total of eight carriages.

The blast occurred near Gokdere village in Elazig province. The railway has been temporarily closed for repairs.

The PKK, which was listed as a terrorist group by Turkey, the United States and the European Union, launched an armed campaign for an ethnic homeland in the mainly Kurdish southeastern Turkey in 1984, sparking decades of strife that has claimed more than 30, 000 lives.
