US uses polygraph tests to hunt source of weapons-supply leak

The United States has turned to polygraph tests in its search for the source of leaks about ammunition shortages during the war with Iran, according to several US media reports.

Fifty military and civilian officials underwent the tests in August as part of the investigation. The inquiry focused on staff at the Joint Staff, the group of senior military leaders that advises the US president.

The investigation was specifically examining the disclosure of information about shortages in weapons supplies. The report did not provide further details about the findings or identify those responsible for the leaks.
