During the Middle East war, Iran has repeatedly struck Iranian Kurdish groups in Iraq's autonomous Kurdistan region, which hosts camps and bases belonging to several exiled rebel groups.

"The Islamic Republic of Iran launched a new wave of missile and drone strikes today targeting... civilian camps of the PDKI," killing one person and wounding his father, the Democratic Party of Iranian Kurdistan (PDKI) said on X.

In a separate attack, two women fighters were killed and other fighters wounded, the party added.

A PDKI official told AFP the fighters were killed in an attack on their positions in the Soran area, nestled in the Zagros mountains near the Iranian border.

On Tuesday, a woman fighter was killed in a drone strike on a position belonging to the exiled Komala party. It was the first such attack against Iranian Kurds in Iraqi Kurdistan since a fragile ceasefire in the US-Israeli war against Iran took effect in the region on April 8.

Iran designates several Iranian Kurdish armed groups as terrorist organisations and accuses them of serving Western or Israeli interests.
