Iran says it has no information about an Iranian unmanned surveillance aircraft the US has reported it shot down last month over Iraq. Iran's Foreign Ministry spokesman, Hasan Qashqavi, says reports of the incident are "ambiguous." He spoke Tuesday during his weekly press briefing. The US military said Monday it shot down the Iranian drone about 100 kilometers northeast of Baghdad after tracking it for about 70 minutes. It said its presence over Iraq was not an accident.
