Iraqi Prime Minister Haidar al-Abadi is to visit Iran on October 20 for talks on Baghdad's battle against the Islamic State (IS) group.
Abadi's office said on October 19 that the one-day trip is part of his bid "to unite the efforts of the region and the world to help Iraq in its war against the terrorist group."
The visit also aims to strengthen cooperation between the two neighbors "in the fields of energy, and housing and construction," the statement said.
IS overran much of the country's Sunni Arab heartland in a lightning offensive in June.
Tehran is a key backer of the Shi'ite-led government in Baghdad.
According to senior Iraqi Kurdish officials, Tehran has deployed troops on the Iraqi side of the border in the Khanaqin area northeast of Baghdad.
