These three are Iranians who are alleged to have come to Iraq illegally as pilgrims after the fall of the regime.

They walked from Iran to Najaf and Kerbala, but they were arrested when they got to the Qadhimia shrine in Baghdad for not having passports or IDs.

They've already been held for a month, but they'll probably be sentenced to three months' imprisonment when their case goes to trial.
