BFnews: A source close to prominent Iraqi cleric Muqtada al-Sader's group reported: A considerable number of Israeli warplanes were seen at al-Asad base in Iraq.
The aircraft reportedly included F-15, F-16, F-18, F-22, and KC-10 jet fighters.
The same source reported: The warplanes carried out their week-long exercises at nights.
The drills were reportedly aimed at preparing to strike Iran's air defense systems, disrupt Iran's radars and attack targets deep inside Iran.
Iraqi officials had not been notified of the exercises, which were conducted in collaboration with the US military.
The United States maintains numerous bases in Iraq, and the Baghdad government is not involved in any of the military deployments taking place there.
