Criticism mounted Thursday of the dramatic airborne rescue from Taliban territory of a kidnapped Western journalist who walked free as four others, including his Afghan colleague, were killed.Negotiators were deep in talks with the Taliban to free New York Times reporter Stephen Farrell and appeared to be progressing well when British commandos intervened with the rescue operation. Farrell, who has dual British-Irish nationality, was freed unharmed, but his Afghan colleague, father-of-two Sultan Munadi, as well as a British soldier and an Afghan woman and child were killed.
