The NATO foreign ministers will meet on Thursday and Friday in the Belgian capital.
"We will discuss what more NATO can do to support Iraq. We are training several hundred Iraqi officers in Jordan. We have received a request from [Iraqi] Prime Minister [Haider] al-Abadi to expand our training mission into Iraq itself," Stoltenberg told reporters.
In April, the first group of officers from Iraq’s national security forces started their NATO training in Amman, Jordan. Some 350 Iraqi officers are expected to be trained by NATO in Jordan in the next six months.
Iraq, along with neighboring Syria, has been suffering from the Daesh terorrist group, which is outlawed in Russia and the Untied States. NATO is not formally engaged in the military campaign against the IS, but individual members are contributing to military efforts against the terror group in both Syria and Iraq.
