Iran arrests dozens in sweeping arrests following Hamas leader's assassination

Iran has arrested dozens of people in the wake of the assassination of Hamas leader Ismail Haniyeh in the capital, Tehran, earlier this week.

Among those arrested are senior intelligence officers, military officials and staff workers at the guest house where Haniyeh was killed.

According to sources familiar with the investigation, speaking to the New York Times, security officials have also targeted Tehran’s international and domestic airports, reviewing months of camera footage from the arrival and departure lounges and examining flight lists.

The sources said the Islamic Revolutionary Guard Corps (IRGC) specialised intelligence unit for espionage is handling the investigation.

Haniyeh's death has provoked an outcry from Palestinians and allies of Hamas and raised concerns about Iran's ability to maintain security within its borders.
