A Russian Sukhoi Su-24 attack aircraft was shot down by a Turkish fighter jet after the former allegedly strayed into Turkish airspace and ignored warnings to change course. 2015 Russian Sukhoi Su-24 shootdown: On 24 November 2015, a Turkish Air Force F-16 fighter jet shot down a Russian Sukhoi Su-24M attack aircraft near the Syria–Turkey border. According to Turkey, the aircraft was fired upon while in Turkish airspace because it violated the border up to a depth of 2.19 kilometres for about 17 seconds after being warned to change its heading ten times over a period of five minutes before entering the airspace. The Russian Defence Ministry denied that the aircraft ever left Syrian airspace, claiming that their satellite data showed that the Sukhoi was about 1,000 metres (1,100 yd) inside Syrian airspace when it was shot down.
