Iran has issued international arrest warrants and requested Interpol Red Notices for leaders and members of several Iranian Kurdish opposition groups based in Iraq and Europe, according to Iran's semi-official Fars News Agency.

The report said the warrants followed more than two years of judicial investigations into allegations including murder, assassination, kidnapping, torture and extortion linked to the groups' activities in Iran's Kurdish-populated regions.

Lawyer Tanhaei, who represents more than 60 plaintiffs, told Fars that Iranian courts had also submitted extradition requests to the Iraqi government and several European countries for members of the Free Life Party of Kurdistan (PJAK), the Kurdistan Democratic Party of Iran (KDPI), Komala and the Kurdistan Freedom Party (PAK).

"The majority of the victims in these cases are ordinary people, particularly Kurdish compatriots and Sunnis living in Kurdish-populated regions," Tanhaei was quoted as saying.

He said the extradition requests were filed after numerous complaints from alleged victims and their families, adding that the number of complainants and alleged crimes exceeded what had previously been reported publicly.

Iran has long accused the Kurdish opposition groups of carrying out armed attacks and separatist activities against the Islamic Republic. The groups, which maintain bases in the Kurdistan Region of Iraq, have previously denied Tehran's accusations, saying they seek to defend Kurdish rights and oppose the Iranian government.

Tehran has repeatedly carried out military strikes against the groups' positions in the Kurdistan Region in recent years, saying the operations are necessary to protect its national security.

Tanhaei called on governments hosting members of the opposition groups to cooperate with Iran's extradition requests, saying they should meet their international obligations by facilitating the prosecution of those accused.
