Israeli attacks on Iran’s South Pars gas field inflicted damage on vital infrastructure, leading Iran to retaliate with strikes on Gulf energy facilities, including Qatar’s Al Laffan LNG complex at the opposite end of the shared gas field.

The gas field spans a total area of 9,700 square kilometers. The world’s largest gas field lies beneath the Gulf and is jointly held by Iran and Qatar. On the Iranian side, it is known as South Pars, while on the Qatari side, it is called North Field or North Dome. Iran depends on the field to fulfill its domestic energy needs, whereas Qatar leverages it for worldwide LNG exports.
