A pilot has died and another injured after a military helicopter crashed during an air show in Russia.
The accident happened at Dubrovichi air field as part of the International Army Games, the Daily Mail reports.
After spinning out of control the Russian helicopter hit the ground, catching fire. Event organisers said a second pilot ejected and was in hospital.
According to the RIA news agency, a Russian air force commander ordered all MI-28 helicopters grounded until the cause of the crash is determined.
The Mi-28 helicopter gunship was part of a flight of helicopters performing aerobatics at the Dubrovichi firing range in Ryazan region, about 105 miles south-east of Moscow.
The surviving crew member managed to eject before the crash and is in a stable condition. While performing a stunt, the helicopter is reported to have banked steeply to one side and started to lose height.
The aerobatics display was part of the International Army Games. The games, which began on Saturday, involves competitions between troops from Russia and several other nations taking place at shooting ranges across the country.
The Mi-28 is a two-seat attack helicopter that replaced older Soviet-built gunships in the Russian inventory. It has been sold to Iraq and Kenya, among others.
It has been reported by the Russian Times that this is the second time the grounding of all Mi-28 assault helicopters has been ordered.
