Iran's first direct attack on Israel on April 13 has brought renewed focus on their air-defence capabilities as Israeli leaders decide how best to respond. The Iranian air force has 37,000 personnel, but decades of international sanctions have largely cut the country off from the latest high-tech military equipment, according to the International Institute for Strategic Studies in London (IISS). Tehran has a squadron of nine F-4 and F-5 fighter jets, one squadron of Russian-made Sukhoi-24 jets, and some MiG-29s, F7 and F14 aircraft, IISS said.
