Afghanistan Violence on 4-20

AP: Iranian, Afghan forces clash at border

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 Sunday.

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.

This is another aspect of the violence in the region that is not widely known.
