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. Turkish Aerospace Industries (TUSAS) was attacked on Wednesday with fighters setting off explosives and opening fire using automatic rifles at the campus of the company that designs and manufactures civilian and military aircraft, unmanned aerial vehicles (UAVs) and other defence industry and space systems. On Friday, Turkey's Ministry of National Defence said it carried out air strikes for the second night in a row in northern Iraq, hitting 34 PKK targets in Hakurk, Gara, Qandil and Sinjar, destroying shelters, warehouses and other facilities. The overnight strikes followed a security meeting that Turkish President Recep Tayyip Erdogan chaired with key ministers and chiefs of the armed forces and intelligence agency in Istanbul. The Turkish government said earlier it had proof that the PKK, listed as a terror group by Turkey, the United States and the European Union, was behind the attack.

A defence company has invented a new futuristic'rifle' that stops rogue drones by hacking into them - and forcing them to fly back to their pilots. DroneShield has developed a software similar to'Google Maps' for drones that instantly locates any drones - and sends them back to their pilots. The firm has previously worked with the British Army and provided assistance to the 2018 Korean Winter Olympics, and their tech is in use at airports. CEO Oleg Vornik remains tight-lipped on the exact cost of the system, but confirmed it ranges from five to seven figures. Mr Vornik also says the system could be used to protect airports from drone incursions - such as the one that brought chaos to Gatwick Airport, bringing it to a standstill for 33 hours before Christmas.

I'm in the cockpit of a Typhoon fighter jet. It's a scene inside an Oculus Rift headset at the new Training and Simulation Integration Facility belonging to defence company BAE Systems. It seems that to make the next great fighter jet, you start by working out what ideas you can pinch from the big consumer tech companies. The burning question on my mind, though, is how the company can even consider replacing cockpit controls with a view of the landscape.
