A Pakistani national convicted of drug trafficking was executed here on Sunday, officials said. Khan Anwar Islam, the first person hanged in Kuwait this year, was arrested in 2002 at Kuwait airport for trying to smuggle 813 grams of heroin in his stomach. Kuwait has executed a total of 72 people, three of them women, since it introduced the death penalty some four decades ago. Most of the condemned have been convicted murderers or drug traffickers.
