Dozens of people have died in a fire at a clinic for drug addicts in Kazakhstan.The blaze broke out early this morning, claiming at least 38 lives. A further 40 patients and staff were rescued from the facility in the southeastern city of Taldykorgan. The cause of the fire is not yet known. An inquiry is underway. Built in 1951, the clinic was one of many state-run healthcare units offering help to addicts in Kazakhstan which lies on the main drug trafficking route from Afghanistan to Western Europe. Deadly fires in centres of this type and other care homes are common in the former Soviet Union where safety standards can be poor.
