Different Taliban Groups Claim Role in Bombing at C.I.A. Afghan Outpost.

Both Afghan and Pakistani Taliban groups claimed responsibility for the suicide bombing this week that killed eight Americans -- seven of them C.I.A. officers -- suggesting that the attack was viewed as a success and could be used to gain recruits and financial support. The competing claims, made Thursday and Friday, did little to clarify the circumstances of the attack, as each group offered a different account of how the C.I.A. base in Khost Province, in southeastern Afghanistan, had been infiltrated on Wednesday.
