Singapore executed 35-year-old Masoud Rahimi Mehrzad, a dual Singaporean-Iranian national, on November 29 for drug trafficking, marking the country's fourth execution in less than a month. Rahimi, convicted in 2013 for trafficking over 31 grams of heroin, had his final appeal dismissed just a day before his execution.

Despite international appeals, including one from Iran's foreign minister urging Singapore to reconsider the execution on humanitarian grounds, the city-state proceeded with the hanging. Singapore's strict drug laws mandate the death penalty for trafficking more than 15 grams of heroin.

This execution is part of a broader trend in Singapore, which has carried out nine executions this year, eight for drug-related offenses. Human rights groups and the United Nations have called for the abolition of the death penalty, citing its lack of deterrent effect. However, Singapore maintains that capital punishment is crucial to maintaining public safety.
