KDPI insurgency (1989–1996)
The insurgency by the Kurdish Democratic Party of Iran surged in 1989, lasting until 1996, as part of the Kurdish separatism struggle. The eruption of the conflict in July 1989 was caused by the assassination of KDPI leader Abdul Rahman Qassemlou by suspected Iranian government agents. The most violent episodes took place in 1990 and 1991, when Kurdish soldiers launched massive attacks on Iranian military bases in Kurdish areas of Iran. This brought heavy retaliation from the Iranian government, aiming to eradicate the KDPI leadership by assassinating Sadegh Sharafkandi and other KDPI leaders in 1992 in order  to disable the Kurdish party's ability to function. The conflict faded with the effective targeted assassination policy of Iran and by 1996 KDPI was no longer able to function militarily and announced a unilateral ceasefire. The conflict claimed hundreds of lives, mostly Iranian government troops and Kurdish militants. Background. In 1979, a wide scale rebellion erupted, as the Kurdish Democratic Party of Iran and its Kurdish allies resisted the new regime. As the Islamic Revolutionary Guard Corps fought to reestablish government control in the Kurdish regions, more than 10,000 Kurds were killed during this process. Pockets of KDPI insurgents  continued to engage in low level fighting up until 1983, as the Iranian forces were diverted to the Iraqi front, with the escalation of the Iran–Iraq War. While most of its military and political activity in Iran was greatly overpowered after the 1979 rebellion, the Kurdish Democratic Party of Iran (KDPI) had continued its opposition activities through 1980s. Nevertheless, the crackdown still continued—'Abd al-Rahman Qassemlou, leader of Kurdish Democratic Party of Iran, was assassinated in July 1989 by the Iranian government. The immediate pretext for the renewed insurgency of KDPI was the event of February 1990, when thousands  of Kurds demonstrated in seven Iranian towns and more than 500 were subsequently arrested. These protests are said to be due to the execution of 17 Kurdish activists. As a result of the crackdown, the KDPI renewed its military activities. Conflict timeline. 1989. Abdul Rahman Ghassmlou, leader of the KDPI, was assassinated by suspected Iranian intelligence agents in Vienna, Austria on July 13, 1989.

In March 1991, Iranian forces crossed over into Iraq and  attacked Iranian opposition forces, including Kurdish forces.

On August 17, 1994, the KDPI said that it has killed 15 Iranian Revolutionary Guards in a clash in western Iran.

On July 10, Iranian agents exploded a car-bomb near a housing complex amidst the main concentration of KDPI refugee camps in northern Iraq.

On July 29, 1996, 3,000 Iranian troops entered Kurdish territory in northern Iraq in search of KDPI guerillas, reportedly killing 20 members of KDPI, while displacing over 2,000 Iranian Kurd refugees.

In January 2014, Iranian forces killed a KDPI party member, while he was disseminating leaflets. In September 2014, in a number of clashes, the KDPI engaged Iranian security for  the first time in many years, killing at least 6 Iranian soldiers. It was unclear whether this was a result of change of policy by the Democratic Party of Iranian Kurdistan (which evaded violence since 1996) or an isolated sequence of incidents. In May 2015, a suspected Iranian attack (allegedly disguised as PKK fighters) on PJAK force on Iranian–Iraqi Kurdistan border resulted in 6 killed—2 KDPI and 4 PKK (or allegedly Iranian agents). In June 2015, a PDKI attack on Revolutionary Guard forces reportedly left 6 people killed. In 2016, the PDKI resumed its military insurgency against Iran. Responses . Iranian officials.
