(updates death toll)
BAGHDAD, Sept 10 (Reuters) - Two roadside bombs exploded in quick succession in a popular market south of Baghdad on Thursday, killing four people and wounding 29, Iraqi police said.
The blasts struck the town of Mahmudiya, about 30 km (20 miles) south of Baghdad, which has been largely quiet for many months.
Mahmudiya was once in the heart of the so-called "Triangle of Death", where radical Sunni and Shi’ite Islamist militants battled it out and settled sectarian scores in 2006 and 2007, killing hundreds of Iraqis.
Violence has fallen sharply in Iraq since those days, but militants are still capable of carrying out frequent bombings. (Reporting by Muhanad Mohammed; Writing by Tim Cocks; editing by Philippa Fletcher)
