Tajikistan sealed its border with Afghanistan this week, after clashes with armed rebels left 48 dead. Security forces are now searching for Tolib Ayombekov, a former rebel who became a commander of the border guard after a 1997 peace deal and is now believed to have taken up arms again. Ayombekov has been a fugitive since he refused to show up for questioning about the July 21 murder of a local security official in southern Badakhshan province, or to turn over men under his command suspected in the slaying. A conflict over control of the cross-border traffic in Afghan opium is said to be behind the fighting.
