Three United Nations' special rapporteurs -- on Iran, summary executions, and torture -- have condemned the recent executions of four members of the Ahwazi Arab minority in Iran.
Following a reportedly unfair trial, they were sentenced to death and executed earlier this month.
The four men -- Ali Sharif and brothers Abdul Rahman Heidarian, Abbas Heidarian, and Taha Heidarian -- were arrested during a protest in the western province of Khuzestan and convicted of "enmity against God" and "corruption on Earth."
In a statement, the three rapporteurs expressed regret that Iran continues to "apply the death penalty with alarming frequency."
According to the statement, at least 140 executions are known to have been carried out since the beginning of 2012, while some other sources put the figure at 220.
