A passenger train travelling from Ankara to Tehran was attacked Thursday in a mine blast thought to have been carried out by Kurdistan Workers’ Party (PKK) militants, a local official said.

The Trans-Asian service was travelling between Genc in the eastern province of Bingol and Suveren, Igdir province, when it was targeted by suspected PKK militants, the Bingol Governor Yavuz Selim Kosger told Anadolu Agency.

A mine laid under the tracks was detonated by remote control, causing damage to carriages and the line but the train was able to continue its journey, according to Worldbulletin.net.

There were no casualties, Kosger said. Security forces have been sent the site of the blast.

PKK is listed as a terrorist organization by Turkey, the U.S. and the European Union.

Turkey has been hit by a number of attacks over the past week — mostly in the country’s southeast — following a ISIL-linked suicide bombing in Suruc, Sanliurfa province, which killed 32 people on July 20.

Across Turkey, more than 1,300 people suspected of links to the PKK, ISIL and a militant left-wing group have been arrested.
