Afghan President Hamid Karzai has criticised the first joint operation by Russian and US agents to destroy drug laboratories in his country. Mr Karzai said he had not been informed of Russia's participation – a sensitive issue in Afghanistan ever since the Soviet occupation ended 21 years ago. He called it a violation of Afghan sovereignty and international law. Russia said more than a tonne of heroin and opium, with a street value of 250 million dollars was destroyed in the raid.
