Afghan government says West holds prisoners illegally in south

KABUL (Reuters) - Afghanistan has accused British and U.S. forces of secretly holding Afghans in jail, saying one man had been held for more than two years while others had "disappeared", further souring ties between Kabul and its Western allies at a sensitive time.

The latest dispute could complicate relations as Washington seeks to implement a security agreement allowing a small force to stay in the country for counter-terrorism and training purposes, a pact incumbent leader Hamid Karzai refuses to sign.
