A source close to prominent Iraqi cleric Muqtada al-Sader, say they have seen Israeli aircraft on the al-Asad air base in Iraq.

The aircraft have been taking part in night time training exercises.  The unnamed source says the exercises are part of preparations to attack Iran.

This is not the first time that Israeli aircraft have operated in Iraq.  In 2008 Iraqi government officials reported that the U.S. was allowing Israeli planes to land and take off form bases in Iraq.
