"Prime Minister al-Abadi informed the Secretary General that the Iraqi government is sending a request to NATO for defence capacity building support," the statement said.
According to the press release, "the Alliance will consider assistance to Iraq in the framework of NATO's Defence and Related Security Capacity Building initiative."
Stoltenberg assured Abadi of NATO's commitment to the continued partnership and support in reestablishing security and stability in Iraq.
The statement says the cooperation between the two sides includes "political dialogue, education and training, response to terrorism, defence institution building, border security and communications."
The Islamic State, also known as the Islamic State of Iraq and Greater Syria (ISIS) or the Islamic State of Iraq and the Levant (ISIL), is a Sunni extremist group formed in 2006. Since 2012, the group has been fighting the Syrian government. In June 2014, the IS extended its attacks on Iraq, proclaiming caliphate on the captured territories.
