Iraq has received the first batch of fighter jets from Russia to help it repel the offensive by Sunni rebels.
The defence ministry said five Sukhoi SU-25 attack aircraft would enter service in "three to four days".
Prime minister Nouri al-Maliki told the BBC last week that his government had signed a deal with Russia and Belarus to supply jet fighters.
The deals are reportedly worth up to $500 million.
