| France's interior minister has said that traces of the poison ricin discovered in a Paris railway station could be linked to a terrorist network with Chechen connections. Nicolas Sarkozy said there was no proof that a ricin attack was being planned against France, but he said there was a possible connection with several men arrested last December for allegedly planning to attack the Russian embassy in Paris. Two vials of the potentially deadly substance were found inside a locker at the Gare de Lyon, according to ministry officials. Mr Sarkozy told French radio that the quantities of the substance were "non-lethal", although they were found with ethanol and acetone. "A mixture of the three can make an extremely nasty poison," he said. |
