Doctors believe “unnatural products” caused the mystery illness of Yegor Gaidar after they failed to find any natural cause, an aide to the former Russian prime minister said on Thursday.
The disclosure came as John Reid, the UK home secretary, told parliament that investigators probing the death of the former Russian KGB officer Alexander Litvinenko had found traces of radioactivity at 12 locations. The locations include two British Airways aircraft grounded at Heathrow on Tuesday after they had made several flights to and from Moscow and other European cities.
