A series of drone attacks have targeted oil fields in Iraq’s semi-autonomous Kurdish region, damaging infrastructure but causing no injuries.

Norwegian company DNO ASA and a U.S.-operated field were among those affected, leading to temporary shutdowns.

No group has claimed responsibility, but Kurdish officials suspect the attacks aim to disrupt the region’s economy and energy sector.

Tensions have risen between Kurdish authorities and Baghdad, with earlier accusations pointing to Iran-backed militias, the Associated Press has reported.

Iraqi officials have denied those claims, warning they could destabilize the country further.
