A 21-year-old man convicted of raping three boys when he was a teenager and sentenced to death has been hanged despite a chief justice's order the case be reviewed, the man's lawyer and a New-York based rights group said Thursday. Makwan Moloudzadeh was executed late Tuesday and his family told to come pick up his body for burial Wednesday, the Human Rights Watch said. "We were expecting an order for retrial by the Supreme Court," Saeed Eqbali, the lawyer of the sentenced man, told The Associated Press. "There would have been no harm in a retrial and it could have saved a life." Authorities detained Makwan in 2006 on charges he had had sexual intercourse with three teenagers, all under the legal age of 18, in the Iranian Kurdish town of Paveh, some 700 kilometers (440 miles) west of Tehran.
