An explosive-laden drone crashed early Thursday near Erbil, the capital of Iraq’s Kurdistan region, with no casualties reported, according to the regional counter-terrorism directorate.

The crash comes amid a sharp rise in drone attacks across northern Iraq, mostly targeting oil fields operated by foreign companies. This week alone, facilities run by Norwegian firm DNO and US companies in areas including Faysh Khabur, Tawke, Baadre, and Duhok have been hit, according to Xinhua.

No group has claimed responsibility for the attacks.
