Three days of drone attacks on oil-fields in Iraq's autonomous Kurdistan region have brought operations at several facilities to a halt and slashed crude output. The taregted sites include fields at Zakho, operated by Norway's DNO [10]; the Sarsang field, operated by US-based HKN Energy [11]; and the Ain Sifni field operated by Hunt Oil [12], all in Dohuk governorate. Kurdistan authorities also said a drone was downed near Erbil airport, which hosts US troops. Nobody has claimed responsibility for the attacks, but Kurdish authorities blamed the Hashd al-Shaabi, or Popular Mobilization Units [13], a paramilitary network aligned with the Baghdad government and backed by Iran. The attacks come amid renewed dispute between Baghdad and the Kurdistan Regional Government over whether the KRG may enter into hydrocarbon contracts with foreign firms. In May, the central government filed a complaint against the Kurdistan region for signing gas contracts with two US companies, including HKN Energy, asserting that all oil and gas deals must go through Baghdad.
