A burning plane and large plumes of smoke are visible at the Mehrabad airport - Iran's busiest airport and main domestic hub - in footage shared by eyewitnesses on social media. Satellite imagery taken on Friday shows multiple aircraft were at the airport.
Iranian state media is also reporting some parts of the airport have been targeted.
It comes after the Israeli military said it was launching a "broad-scale new wave of strikes" in the country. It previously targeted the airport on 4 March, saying its strikes dismantled defence and detection systems that were a threat to the Israeli Air Force, which included the helicopter manufacturing section of the airport.
It is not yet clear which parts of the airport has been bombed in the fresh attack but witnesses say tonight's bombardment has been much more intense.
