Czech and Russian military officials say that at least six people were seriously injured on May 23 in a fire aboard a Russian aerial survey AN-30 aircraft.
Reports say the fire was caused by malfunctioning landing gear as the plane was preparing to land at Caslav airbase near Prague.
A Czech Defense Ministry spokesman told journalists that 23 military personnel -- 14 Russians, and nine Czechs -- were aboard the plane.
Russian Defense Ministry spokesman Igor Konashenkov said the plane was on an observation flight above the Czech Republic under the Treaty on Open Skies
