In 2002 we had a team chasing a group of Russian speaking caucasian looking types that the Afghans called Chechens. We also had a number of reports of Chechen fighters, with their families, in country. Most of them, not all by any means, were heading towards a border to get out of the country.

My impression was that these were small groups of exiles who ended up in Afghanistan because they had no other place to go. Afghanistan was not the first choice of refuge for folks on the run with their families.
