British Airways was warning up to 33,000 passengers Thursday that traces have been found on board two planes of the radiactive poison linked to the death of former Russian spy Alexander Litvinenko as his inquest was adjourned. Litvinenko, a fierce critic of Russian President Vladimir Putin, fell ill on November 1 and died on November 23, with large quantities of the radioactive substance polonium-210 having been discovered in his urine.
