Iran has temporarily closed its airspace to nearly all flights except for international civilian arrivals and departures, according to an official aviation notice issued early Thursday. The notice stated that Tehran’s airspace would remain closed until January 15, with only limited operations allowed under approval from the Civil Aviation Authority.

The decision comes amid escalating anti-government protests, growing international scrutiny, and heightened security concerns across the country. Human rights groups claim that thousands have been killed or injured since demonstrations began in late December, though Iranian authorities have not released official casualty figures.

U.S. President Donald Trump said he was informed that executions of protesters in Iran had been halted, warning that Washington would take “very tough measures” if they resumed. G7 foreign ministers condemned the “deliberate use of violence” against demonstrators and urged Iran to show restraint and respect human rights. Iranian officials, meanwhile, accused the United States and Israel of supporting unrest and terrorism, allegations denied by Western nations.
