Turkey's government says its military struck sites on Wednesday night in Iraq and Syria linked to Kurdish militant group the PKK, after blaming it for an attack near Ankara that killed at least five people.

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

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.”
