Iraq Prime Minister Haider al-Abadi has reportedly ordered the Iraqi Air Force to conduct strikes against ISIS positions inside Syria.
This is the first time that Iraqi fighter jets were ordered to carry out such airstrikes across the border.
Abadi was quoted by Reuters as saying: "We are determined to chase terrorism that tries to kill our sons and citizens, wherever it is found, so we gave orders to the air force command to strike Islamic State positions in (the Iraqi town of) Hosaiba and Albu Kamal inside Syrian territory as they were responsible for recent bombings in Baghdad.
"The heroes of the sky executed the operation and responded to the terrorists with amazing success."
The air force deployed F16 fighter jets to destroy ISIS headquarters, in a bid to avenge for the recent series of car bombing attacks across Baghdad.
ISIS has lost its control of eastern Mosul in Iraq to an Iraqi military offensive backed by the US.
The Iraqi Air Force conducted the strikes in the Syrian towns of Boukamal and Husseibah across the border, reported The Associated Press.
Brigadier general Tahseen Ibrahim, who spoke on behalf of Iraq’s Defence Ministry, was also quoted by the news agency as saying that the airstrikes were coordinated with Damascus coordination with the Damascus Government, in Syria.
The hits were conducted through a joint intelligence-sharing and command centre in Baghdad, involving Syria, Iraq, Iran and Russia, reported The Washington Post.
Pentagon spokesman captain Jeff Davis was quoted by Reuters as saying: “Yes we were aware, yes we supported it as well with information.
“It is a good strike, it is a valid strike, it was a strike against ISIS targets.”
