On 22 September 2007, Iraqi President Jalal Talabani criticized the United States for arresting the Iranian and called for his immediate release. Talabani argued he is a civil servant who was on an official trade mission in the Kurdish Region and stated Iraqi and Kurdish regional government representatives were aware of the man's presence in the country. "I express to you our outrage for these American forces arresting this Iranian civil official visitor without informing or cooperating with the government of the Kurdistan region, which means insult and disregard for its rights", Talabani wrote in a "letter of resentment" to Ryan Crocker, U.S. ambassador to Iraq, and Gen. David Petraeus.
