A drone struck an arms depot in an attack on the headquarters of an Iranian Kurdish opposition group in the town of Dekala in Iraq's Kurdistan region on Wednesday, wounding two fighters, security sources said.

Iran has long accused Iraq's autonomous northern Kurdish region of sheltering militant groups involved in attacks against the Islamic Republic, with Iran's Revolutionary Guards in turn repeatedly targeting their bases.

Reuters reported this week, as the United States and Israel pounded Iranian targets, that Iranian Kurdish militias have consulted with the US in recent days about whether, and how, to attack Iran's security forces in the ​western part of the country.

Iranian Kurdish groups training to mount an attack?

According to three sources with knowledge of the matter, the Iranian Kurdish coalition of groups based on the Iran-Iraq border in the semi-autonomous region of Iraqi Kurdistan has been training to mount such an attack in hopes of weakening the country's military, as the United States and Israel pound Iranian targets with bombs and missiles.

The goal would be to create room for Iranians opposed to the Islamic regime to rise up now that Supreme Leader Ali Khamenei and other top officials have been killed since the US-Israeli attack began on Saturday, two of the sources said.

A final decision has not yet been made on the operation and its possible timing, the sources added, who spoke on condition of anonymity to talk freely about sensitive military planning.
