Crude oil futures bounced back on surprisingly strong US economic data, falling US stockpiles, and drone attacks on oil infrastructure in Iraq's Kurdistan region.

Drones struck oilfields in Iraqi Kurdistan on Thursday, with officials pointing to Iran-backed militias as the likely source of attacks this week that have slashed the region's oil output by more than half.

“The drone attacks in Kurdish energy sites grew out of a sequence of drone attacks since 19 June on Kurdish security forces, where Iraqi militias were claiming that Kurdistan was supporting Israeli and US strikes on Iran,” Michael Knights, a senior fellow at The Washington Institute, told MEE.
