Will U.S. aid be misused? No guarantee at Afghan ministries - auditors

WASHINGTON (Reuters) - Sixteen Afghan government ministries cannot ensure that direct American aid to the war-ravaged country will not be misused, auditors privately warned the American government, a U.S. watchdog said in a report released Thursday.

The disclosure could further aggravate ties between the United States and Afghanistan, already being tested by Afghan President Hamid Karzai's refusal to sign a bilateral security pact allowing some U.S. troops to stay after NATO wraps up its combat mission this year.
