May 22, 2007 -- Iran has reportedly arrested more than 15 people after they allegedly called for a demonstration in the northwestern city of Tabriz to mark the anniversary of the publication of a cartoon offensive to Iran's Azeri minority.
The ISNA news agency says the individuals were arrested in Iran's East Azerbaijan Province.
The government-run newspaper "Iran" in May, 2006, published a cartoon depicting an ethnic Azeri as a cockroach, sparking days of clashes between police and protesters which left four dead.
Azeris form a majority in East Azerbaijan Province.
