A deadly “terrorist” attack targeted a Turkish aerospace company in the capital Ankara on Wednesday, according to government officials.

“A terrorist attack was carried out against the facilities of Turkish Aerospace Industries Inc. (TUSAS) in Ankara Kahramankazan. Unfortunately, we have martyrs and injured people after the attack,” Interior Minister Ali Yerlikaya said on X.

A social media video verified and geolocated by CNN showed the moment an explosion rocked the TUSAS headquarters. After the explosion, a person with a gun is seen running into what appears to be a parking lot.

Ankara Mayor Mansur Yavas said he was “saddened” by the attack on TUSAS, a major defense contractor.

TUSAS was incorporated into Turkey's Ministry of Industry and Technology in 1973 to reduce the country's “foreign dependence in the defense industry,” according to its website.

Turkish Justice Minister Yilmaz Tunc said an investigation into the attack had been launched.

The US State Department is “following reports” of the attack, a spokesman told CNN.

After the attack, the company's chief executive, Mehmet Demiroglu, left a high-profile defense trade fair early to return to Ankara, state news agency Anadolu reported.

The attack occurred as Turkish President Recep Tayyip Erdogan was in the Russian city of Kazan to attend the annual BRICS summit.
