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

Five people have been killed in an apparent terror attack in Turkey at the headquarters of a defence and aerospace company. Turkey has blamed Kurdish militant group the PKK for the attack and has launched strikes on its sites in Syria and Iraq.

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.”
