Several people have been injured in an explosion near the Turkish ruling party headquarters and the governor's office in the eastern province of Van, according to Turkey's state-run news agency.
The Anadolu agency said the explosion occurred on Monday morning on the first day of Eid al-Fitr, an Islamic holiday.
Burhan Kayaturk, a member of parliament from the ruling AKP party, told private channel HaberTurk that there are 11 wounded.
Ambulances have rushed the wounded to nearby hospitals and many police cars and fire engines have been dispatched to the area.
Turkey has suffered a string of attacks in recent months from both Kurdish militants linked to the outlawed Kurdistan Workers' Party or PKK as well as from Islamic State, resulting in dozens of casualties.
