Three people are dead after a "terrorist attack" outside the premises of the Turkish aerospace and defence company Tusas in <a href="https://www.thenationalnews.com/mena/iraq/2023/10/05/iraqi-defence-minister-visits-ankara-after-turkish-strikes-on-kurdish-region/" target="_blank">Ankara</a> on Wednesday, the country's Interior Minister said. Ali Yerlikaya said 14 people were injured and two attackers killed in the incident, in which an explosion was heard across the capital. Security forces, ambulances and firefighters were dispatched to the site in the north-west of Ankara, the pro-Turkish government television channel NTV reported. Gunshots were heard following the explosion at the entrance gate of Tusas's premises, the Turkish news channel Haberturk said. NTV also reported that security forces and terrorists were "clashing" in the area and that an unspecified number of people had been taken hostage. Personnel at the site were directed to shelters, the channel added. No group has claimed responsibility for the attack. Turkey experienced a wave of suicide bombings in 2015 and 2016, mostly attributed to ISIS and the Kurdistan Workers' Party (PKK), a Kurdish militia listed as a terrorist organisation by Ankara. Since then, Turkey has had a period of improved security, although attackers still occasionally hit crowded areas and members of the security forces. <a href="https://www.thenationalnews.com/mena/2023/02/24/turkey-says-main-suspect-in-istanbul-bombing-killed-in-northern-syria/" target="_blank">Six people were killed and dozens wounded</a> when an explosion rocked the bustling <a href="https://www.thenationalnews.com/world/2022/11/14/istanbul-explosion-turkey-accuses-kurdish-pkk-as-arrest-made/" target="_blank">Istiklal Avenue</a>, close to <a href="https://www.thenationalnews.com/world/europe/erdogan-inaugurates-mosque-in-istanbul-s-taksim-square-1.1231493">Taksim Square</a> in central Istanbul, in November 2023.
