Western Iran clashes (2016–present)

2016–present clashes in West Iran refers to the ongoing military clashes between Kurdish insurgent party Democratic Party of Iranian Kurdistan (PDKI) and the Iranian Revolutionary Guards, which began in April 2016. Kurdistan Freedom Party (PAK) and Komalah expressed their support to the Kurdish cause of PDKI as well, with both clashing with Iranian security forces in 2016 and 2017 respectively. In parallel, a leftist Iranian Kurdish rebel group PJAK resumed military activities against Iran in 2016, following a long period of stalemate.

The 2016 clashes came following a background of what PDKI described as "growing discontent in Rojhelat". The commander of the PAK military wing described their engagement and declaration of hostilities against the Iranian government were due to the fact that "the situation in eastern Kurdistan (Iranian Kurdistan) has become unbearable, especially with the daily arbitrary executions against the Kurds [in Iran]".

Background
Iran has a significant 8 million strong Kurdish minority, concentrated in the West of the country, many of whom are Sunni. The Kurds spread across the Iranian provinces of West Azerbaijan, Kurdistan, Kermanshah and Ilam. Kurdish separatism is a theme in several Middle Eastern nations, and Kurdish movements have engaged in conflicts also in Syria (Kurds in Syria), Iraq (Kurds in Iraq), and Turkey (Kurds in Turkey) to promote national ambitions.

The PDKI had announced the "restart [of] armed resistance against the Islamic Republic of Iran" on 25 February. The PDKI explained that their return to arms was due to "growing discontent in Rojhelat". According to Al-Monitor analysis, since March 2015, the PDKI has dispatched several teams of its fighters and political cadets into Iranian Kurdistan. The PDKI announced in March 2016 that it was giving up a two-decade ceasefire with the Iranian government and returning its guerrilla fighters to Iran, but vowed not to initiate hostilities unless attacked. In September 2016, PDKI released a statement that their return to militancy was also motivated by Iran's nuclear deal.

Commander of the PAK military wing described their engagement and declaration of hostilities against Iranian government due to the fact that "the situation in eastern Kurdistan (Iranian Kurdistan) has become unbearable, especially with the daily arbitrary executions against the Kurds".

Belligerents
The Kurdish separatist movements of PAK and KDPI were the first to initiate insurgency in the first half of 2016. In October 2016, PJAK separately announced to resume its militant activities, which had largely been postponed since 2011 unilateral cease fire. On 23 October 2016, the leader of Komala party Abdullah Muhtadi called the movements of East Kurdistan to form a joint front, as to "merge their separate enclaves is necessary in order to face their common enemy—Iran". Komalah officially announced initiation of militant activity in June 2017.

On behalf of the Islamic Republic of Iran, the security forces involved in fighting include the Revolutionary Guards units, the Basij and the Islamic Republic of Iran Border Guard Command.

Foreign involvement
Amidst of Iran–Saudi Arabia proxy conflict, Iranian authorities blame Saudi intelligence agency for supporting the unrest. However, Saudi officials deny involvement.

According to a Stratfor analysis, PAK and KDPI have appealed directly to Riyadh in their calls for funding and "countries with a vested interest in exacerbating Iran's domestic problems—such as Saudi Arabia may agree to help the Kurds". Saudi Arabia may have been providing financial support to all three Kurdish insurgent groups through its consulate in the Iraqi Kurdistan, which is newly opened.
