SIRNAK, Turkey (AA) - At least 11 police officers were martyred Friday when PKK terrorists detonated a truck bomb near a security checkpoint in the southeastern Turkish province of Sirnak, the regional governor's office said.

The office said the blast also injured 75 police officers and three civilians.

The terrorist attack took place at 06.45 am (0345GMT) with a bomb-laden truck targeting a checkpoint some 50 meters from riot police unit headquarters in the town of Cizre, Sirnak, the governor's office added.

The blast caused extensive damage to the police building. Nearby houses and workplaces were also damaged.

Security forces are currently searching for the perpetrators.

Turkey’s Supreme Board of Radio and Television has banned all broadcasts about the deadly attack in the interest of public safety and the ongoing investigation.

The PKK -- also listed as a terrorist organization by the U.S. and the EU -- resumed its 30-year armed campaign against the Turkish state in July 2015.

Since then, more than 600 security personnel have been martyred and more than 7,000 PKK terrorists have been killed.
