The situation across Iraq remains unstable, as terrorists continue to stage regular attacks on Iraqi troops and civilians.
By March 2019, Iraqi forces, backed by US-led coalition airstrikes, retook all the territories previously occupied by the terrorists. However, the Daesh* terror group is still present in Iraq and Syria and continues to stage sporadic attacks.
*Daesh (also known as ISIS/ISIL/IS) is a terrorist group banned in Russia
