A Ukrainian military plane flew within 3-5km of flight MH17 just before the Malaysian aircraft crashed, the Russian Defence Ministry has claimed. Moscow has also denied supplying pro-Russian rebels with BUK missile systems – the weapon that is suspected of bringing down the passenger plane – or any other military hardware.
It said it detected the Ukrainian SU-25 combat jet on radar and noticed an increase in radar activity just before the Malaysian Airlines jet carrying 298 people, including 10 Britons, was destroyed. It also said Ukrainian air defence forces had three or four battalions of BUK-M1 systems on combat duty on the day of the crash. However, Ukrainian President Petro Poroshenko said all his planes in the area were grounded at the time of the downed aircraft.
