The European Union on Tuesday condemned the hangings in Iran of 29 people convicted of murder, drug trafficking and other crimes, and called on Teheran to place an immediate moratorium on more executions. The 27-nation bloc said Teheran's decision to hold the executions Sunday and to publicize them in the national media "is an affront to human dignity." The hangings brought to about 150 the number of people executed in Iran so far this year. The EU also said Tuesday that capital punishment "cannot form the basis" of a fair anti-crime policy. It said the dissuasive effect of the death penalty has never been proven and the punishment cannot be reversed if a person is convicted in error.
