KABUL (Reuters) - Afghanistan on Thursday freed 77 prisoners captured by foreign troops, despite opposition from Britain and NATO-led forces which said they could pose a security threat.

Afghan President Hamid Karzai's government has long complained that foreign forces have locked up many Afghans on dubious grounds and with no proper judicial process. A similar release last month caused tension with the United States.
