Singapore hanged a third prisoner in two weeks on Thursday for drug trafficking despite calls for the city-state to halt capital punishment for drug-related crimes, reported AP.

The Central Narcotics Bureau said Mohamed Shalleh Abdul Latiff, a 39-year-old Singaporean, was executed at Singapore's Changi Prison after being accorded due process under the law. He was sentenced to death for trafficking 54 grams (1.9 ounces) of heroin, an amount "sufficient to feed the addiction of about 640 abusers for a week," it said in a statement.
