Iraq has agreed to keep tighter controls on flights moving through its airspace from Iran to Syria, AP reported.
The move came after U.S. Secretary of State John Kerry visited the region to plead with Iraq to search planes traveling from Iran to its war-torn neighbor.
Government spokesman, Ali al-Moussawi told AP that they would be conducting more random searches to ensure that Iranian weapons did not reach the Syrian regime's army using Iraqi airspace.
Iran is one of the only regional supporters of President Bashar al-Assad's government and had previously been relying on Iraq's lack of checks to get through their weapons shipments.
On Thursday activists in Syria reported that rebel fighters had taken down a weapons plane from Iran on its way into Damascus airport.
