Aftermath
Iran responded a week later by attacking Kurdish villages in the border area of Panjwin inside Iraq using helicopter gunships. According to Iraqi border guards officials, the area attacked by Iran was not considered a stronghold of PJAK, that appeared to have been the target of the raid. According to the ICRC, more than 800 Iraqi Kurds have been forced from their homes by the recent cross-border violence. See also
