Iranian state TV says a 6-magnitude earthquake has jolted a western region near the border with Iraq.

There were no immediate reports of casualties or major damage from the temblor, which struck Monday near the site of a 7.2-magnitude quake that caused more than 600 deaths in November.

Iran is prone to near-daily quakes as it sits on major fault lines. In 2003, a 6.6-magnitude quake flattened the historic city of Bam, killing 26,000 people.
