Iraqi security officials are now telling CNN there are no casualties among Iraqi security forces following the attacks on the al-Asad airbase in Anbar province and the attacks in Erbil.

This is updated information from security officials following the initial assessment. Earlier Wednesday, an Iraqi security source told CNN that there had been Iraqi casualties.

"We were initially hearing that there were casualties -- it was unclear how many or if they were killed or wounded -- on the Iraqi side," CNN's Arwa Damon reported from Baghdad.

"Now we're hearing from two other sources that there may not be casualties -- that does make sense given how chaotic the aftermath of these strikes can be."
