UNITED NATIONS, Dec 14 (Reuters) - Iran was ousted from a United Nations women's group on Wednesday for policies contrary to the rights of women and girls, a move proposed by the United States after Tehran's crackdown on protests over the death of a young woman in custody.Iran's clerical rulers have faced the biggest protests in years since September when 22-year-old Kurdish Iranian woman Mahsa Amini died in the custody of the morality police who enforce strict dress codes.Iran, 17 other states and the Palestinians, in a letter to ECOSOC on Monday urged members to vote no to avoid a "new trend for expelling sovereign and rightfully-elected States from any given body of the international system, if ever perceived as inconvenient.""Even a lot of countries disgusted by Iran's behavior would have preferred something milder, like temporarily suspending Iran from the CSW," Gowan said.The Islamic Republic on Monday hanged a man in public who state media said had been convicted of killing two members of the security forces, the second execution in less than a week of people involved in protests."
