Iran's Islamic Revolutionary Guards Corps (IRGC) says it has killed six members of a Kurdish militant group that took part in a July attack on an Iranian border post near Iraq.

Iranian officials say the six were part of a group from the Party of Free Life of Kurdistan (PJAK), a Kurdish opposition group, who attacked the border post on July 20, killing 10 IRGC members.

The outlawed PJAK seeks self-governance for Iran's Kurds and has links to Turkey's militant Kurdistan Workers Party (PKK). It operates in the northern Iraqi border area with other armed Kurdish groups.

There is little coordination between Iranian and Iraqi forces over security of the remote mountainous border that has also been used by the Islamic State (IS) group to enter Iran.

In June 2017, IS militants carried out coordinated attacks at the parliament building in Tehran and the mausoleum of Iranian Supreme Leader Ayatollah Ruhollah Khomeini, south of the capital. At least 18 people were killed in the incident.
