Iran has announced the resumption of its airspace closures in the western and central regions.

Iran’s Mehr News Agency reported on the 2nd that a spokesperson for the Ministry of Roads and Urban Development, Majid Ahwan, announced that all flights in Iran’s western and central territories will be grounded. This comes just four days after Iran allowed international transit flights to use its western and central airspace.
Ahwan stated that the decision was made by a coordination committee of the Iranian Civil Aviation Organization following an assessment of security and safety concerns.
Affecting airports in both southern and northern parts of Iran, including Mehrabad Airport in Tehran and Imam Khomeini International Airport, the closure of these facilities will continue. However, the eastern part of Iran, which reopened on the 25th of last month, remains unaffected, allowing international transit flights as well as domestic and international flights taking off from and landing at airports in the eastern region to continue.
On the 28th of last month, Iran announced the reopening of its western and central airspace to international transit flights. The reason behind the decision to close the airspace again four days later is not clear. According to Mehr News Agency, some speculate that Israel might violate the ceasefire agreement and launch a new round of airstrikes against Iran.
In response to this, Israel launched a large-scale airstrike on Iran early on the 13th of June, closing its airspace and retaliated with ballistic missiles and drones. On the 21st of Eastern Time, President Trump of the United States announced that U.S. forces had bombed three nuclear sites in Iran. On the 23rd, Iran launched retaliatory missile strikes against the U.S. Air Force Base at Qatar’s Udairah. On the 24th, a ceasefire between Iran and Israel was declared.
