Iraq has suspended Iranian flights to Baghdad following US threats of sanctions, as US officials warned of shutting down Iranian carriers by September 23. The move comes amid escalating tensions between the US and Iran, with US Treasury Secretary Scott Bessent announcing plans to target airlines seven months into the conflict. Iraqi authorities acted swiftly, ordering the civil aviation authority to halt flights starting Wednesday, according to sources. The decision follows pressure from Washington, which has warned of secondary sanctions on airports that facilitate Iranian air travel. Iran's aviation officials have been negotiating with Oman and Iraq to find alternative routes, but the situation remains uncertain. The suspension highlights the growing impact of US sanctions on regional air connectivity, affecting both commercial and diplomatic travel. As the conflict continues, the future of Iranian flights in the region remains under threat.
