WASHINGTON, Mar 19 – Oil prices rose above $110 (£82.78) a barrel after Iranian media reported an airstrike hitting a facility on the world’s largest natural gas field.The Brent crude oil benchmark hit $112 a barrel in early Thursday trade in Asia, more than 5% higher than Tuesday’s prices. The price has since fallen slightly.The benchmark UK gas price also jumped by 6% to 143.53p a therm before falling back to around the 140p mark.The surge followed reports Iran’s petrochemical complex on the South Pars gas field had been hit. Several hours later, Qatar reported that there was “extensive damage” at the Ras Laffan industrial site following threats from Iran.While the price of both oil and gas spiked, they remained below highs seen earlier in the conflict.Oil reached $116.78 a barrel on 9 March, while UK gas reached 162.55p a therm on 3 March.Iran’s oil ministry said a fire at the petrochemical complex was under control, according to Tasnim, a news agency affiliated with the Islamic Revolutionary Guard Corps.Iran’s military warned it would take “decisive action” in response to the strike on its energy infrastructure.“As previously warned, if the fuel, energy, gas, and economic infrastructures of our country are attacked by the American-Zionist enemy, in addition to a powerful counterattack against the enemy, we will severely strike the origin of that aggression as well,” the military said in a statement published by Tasnim.“We consider targeting the fuel, energy, and gas infrastructures of the countries of origin legitimate and will retaliate strongly at the earliest opportunity.”Qatar also operates facilities on the gas field, which it calls North Dome.But the country, which produces a fifth of the world’s liquefied natural gas, had halted production earlier in March in response to the conflict.Qatar’s foreign ministry spokesman Majed Al Ansari said strikes against energy infrastructure “constitutes a threat to global energy security”.Just after 1815 GMT, the Qatari interior minister said it was responding to “a fire in the Ras Laffan area following an Iranian targeting”. Qatar’s petrol firm QatarEnergy later said there was “extensive damage” at the site.The interior minister said just after 1900 GMT that it had “initially brought the fire in Ras Laffan under control, with no injuries reported”.Ras Laffan was among the sites listed by Iran in a warning that it would take “decisive action” after its South Pars gas field facilities were reportedly hit by Israeli strikes.
