Iran has announced the closure of its airspace until tomorrow, including the closure of Imam Khomeini International Airport, according to reports from a news agency, while Israeli airlines announced that operations have resumed as usual.

This decision follows escalating tensions between Iran and Israel, prompting heightened security measures across the region.

In addition to the closure of its airspace, internal flights to major cities in Iran have been suspended until further notice, adding to the disruption caused by the ongoing situation. The closure affects not only domestic travel but also international flights, with airlines like Etihad Airways cancelling flights to Israel, Oman, and Jordan.

$1bn loss to Israel

Meanwhile, Israeli media outlets claimed significant financial losses incurred by Israel as a result of the recent Iranian attack. The attack, which utilized missiles intercepted by Israel's Iron Dome system, has led to the destruction of valuable infrastructure and assets.

Reports suggest that Iron Dome missiles, worth over $1 billion, were used to defend against the incoming threat.
