Iran's state news agency says three men convicted of killing a prosecutor in the country's restive border region with Pakistan have been executed.
IRNA says Omid Piri, Alireza Dahmardeh, and Iman Galavi were hanged publicly on April 26 in front of the family of the slain prosecutor and residents of Zabol, a town in Iran's southeastern province of Sistan-Baluchistan.
IRNA says the executions took place at the same spot where public prosecutor Mousa Nouri was gunned down in November along with his driver.
The case had been reviewed by Iran’s Supreme Court, which upheld the verdict against the three.
Nouri had been considered one of the toughest prosecutors fighting against opium and other drug-smuggling networks that use routes leading from Pakistan and Afghanistan over Iran's rugged hills and deserts.
