At least one person has reportedly been injured when unidentified armed men launched an attack against an office of Turkey’s ruling Justice and Development Party (AK Party) in the country’s largest city of Istanbul.
Party sources, speaking on condition of anonymity, said the assailants raided the building in Beyoglu district of the city late on Saturday, opened fire and lightly injured one person, Haberler.com news portal reported.
The gunmen fled after special operations forces rushed to the scene and responded.
Security forces have launched an investigation into the attack. A suspect has been detained in connection with the incident.
Prime Minister Ahmet Davutoglu, the AK Party leader, strongly condemned the attack, saying those responsible will be brought to justice.
AK Party provincial head, Selim Temurci, said the injured person received a gunshot wound in the arm, and was dismissed from hospital after being treated.

On April 1, an armed man, wearing a military-style jacket, stormed an office of AK Party in Istanbul’s Kartal district.
He ordered all those inside to leave, and reached the top floor of the seven-story building. The assailant then broke a number of windows and hung a Turkish flag with a sword on it.
Special Forces intervened shortly afterwards and arrested the gunman.
The incident came a day after Revolutionary People’s Liberation Party-Front (DHKP-C) gunmen raided the sixth floor of the Caglayan courthouse and took prosecutor Mehmet Selim Kiraz hostage.

Kiraz was investigating the killing of Berkin Elvan, who died on March 11, 2014 after spending 269 days in a coma due to injuries inflicted by police in early summer 2013.
The prosecutor succumbed to his injuries in hospital late on March 31 after a six-hour hostage drama in which security forces killed the man’s two captors.
