A large explosion in Ankara sent smoke billowing over the headquarters of one of Turkey’s most important arms companies. CCTV footage showed a man and a woman wielding automatic weapons as they opened fire on staff trying to flee. Ali Yerlikaya, Turkey’s interior minister, confirmed the pair were “neutralised.”

Turkey is carrying out cross-border airstrikes against Kurdish militant groups it accused of a deadly bombing and gun attack on its capital.

Turkey launched fresh air strikes on Kurdistan Workers Party (PKK) militants in Syria and Iraq overnight, hitting 47 targets, in response to a gun attack that killed five people in Ankara, Defence Minister Yasar Guler said on Thursday.
