Four Greeks were undergoing medical tests for possible contamination by a radioactive substance that killed a former KGB spy in London last month, private Greek television said Saturday.
The four people were recently in London and stayed at the same hotel as Alexander Litvinenko, who died on Nov. 23 after being poisoned by polonium-210, private Antenna TV said, quoting Deputy Health Minister Thanasis Yiannopoulos.
The four people - who were not identified - were undergoing blood and urine tests at the state-run Dimokritos nuclear research center, Antenna reported. Results were expected early next week.
