US Soldiers inspect a potato field where an Iraqi farmer unearthed a cache of unexploded shells, usable as ordinance for a roadside bomb, in Shakiriyah, south of Baghdad on March 19, 2008. US forces were alerted to the arms cache by an Iraqi sheikh who inexplicably set a lively Arabic song as background music to a mobile phone video he had taken of a row of unexploded shells unearthed from a potato field. The message to US military commander Captain Cliff Kazmarek was clear -- his community had uncovered a munitions cache and he was now claiming the reward. AFP PHOTOT/ALI YUSSEF
