Afghan police clashed with Iranian forces at the southwestern border between the two countries, leaving one civilian dead and two Iranian officers wounded, officials said. An Interior Ministry statement said Sunday that the incident happened a day earlier in the village of Pul-e-Abreshum in Nimroz province after an Iranian patrol entered Afghanistan. Afghan police dispatched a unit to the village and a gunbattle ensued. A teacher from the village was killed during the firefight, said provincial police chief Gen. Ayub Badakhshi. Two Iranian officers were wounded, the statement said. The long and porous border between the two countries is used by smugglers to traffic drugs into Iran. Many Afghans also cross illegally into Iran from the area. Border clashes are common.
