Ali Arbabi was hanged in a prison in the town of Iranshahr at dawn in the south-eastern province of Sistan-va-Baluchistan, according to a state-run daily. In recent months, Iranian authorities have stepped up executions in the restive province in what many Baluchis believe is a response to a spate of attacks by dissidents on government and security officials.
