The outlawed Kurdistan Workers’ Party (PKK) has claimed responsibility for an attack on a Turkish state-run defence company near the capital, Ankara, that killed five people and wounded 22.

The “act of sacrifice” in Ankara “was carried out by a team of the immortals battalion” of the PKK, the group said on the Telegram messaging app on Friday.

On Friday, the Reuters news agency quoted security sources as saying Turkey’s National Intelligence Organisation (MIT) had hit a total of 120 PKK targets in Iraq and Syria since the attack near Ankara.

Turkish drone strikes killed 27 civilians in north and east Syria in a 24-hour military escalation following the deadly attack, the Syrian Observatory for Human Rights, a war monitor, said on Friday.

It said it documented 45 drone strikes and four by fighter jets targeting infrastructure including water and power networks and gas stations. The Turkish army rejects claims it hits civilian targets.
