The Romanian soldiers were on patrol north of Qalat in the southern province of Zabul when their vehicle drove over the device. Romania has a 646-strong contingent in Afghanistan. A total of 562 of those troops have been deployed as part of the International Security Assistance Force (ISAF) and 84 as part of US-led coalition troops.
