Policemen stand as the area is fumigated outside Chhattisgarh Institute of Medical Sciences (CIMS) hospital where several women, who underwent a sterilization surgery at a government mass sterilisation "camp", are treated in Bilaspur district, in the eastern Indian state of Chhattisgarh, November 13, 2014. Tainted or sub-standard drugs probably led to the deaths of 13 Indian women after sterilization surgery at a family-planning "camp," and owners of the factories that produced them have been summoned for questioning, a senior official said on Thursday.
