CLEVELAND, Ohio -- The Sheffield Lake man facing terrorism charges told a FBI informant that if war broke out in the U.S. between Muslims and non-Muslims, he would "cut off the head of his non-Muslim son if necessary," according to a criminal complaint.

Amir Said Abdul Rahman Al-Ghazi's comment about his son is revealed in the 33-page complaint filed Friday by the FBI in U.S. District Court.

The complaint also states that when asked by the criminal informant what he thought of videos showing the beheading of U.S. citizens by Islamic State militants, his response was: "You really wanna know what I think? ... I support that. ... That's our way of life. ... Yeah, I go for this. ... I'm uh. ... I do this."

Al-Ghazi, 38, faces charges of supporting a terrorist organization, the Islamic State, also known as ISIS. A federal judge ordered Friday afternoon that Al-Ghazi be held in custody until a hearing on Wednesday.

Al-Ghazi made comments to a total of three FBI informants, according to the complaint, at times stating he thinks it's okay to behead Christians, Jews, and atheists. Al-Ghazi also referred to Iraqis as his "brothers and sisters," the complaint states, and told one informant that he had ideas for a terrorist attack in the U.S., including attacking a police station or derailing a train.

But, Al-Ghazi said he wasn't interested in becoming a martyr, but rather told an informant that he "wanted to get away with it," the complaint states.

Al-Ghazi also posted on various social media sites including Facebook and Twitter messages in support of ISIS. According to the complaint, he also commented on a message board that "We are all Islamic state citizens. This isn't some gang in the desert you're fighting. This is WW3 the beginning has just begun."

He also told one informant that he was trying to recruit people to join ISIS, the complaint states. He also tried to buy an AK-47 to use in propaganda videos. He told an informant that he already had a ski-mask and a "green screen," and that he'd already bought a machete. He made references to conducting "cyber jihad."

The complaint states that Al-Ghazi used Google Drive and YouTube to share early versions of propaganda videos he had made with confidential informants.

Al-Ghazi, who changed his name from Robert C. McCollum early this year, has a lengthy criminal record in Cuyahoga Common Pleas Court. Since 1996, Al-Ghazi has pleaded guilty on nine occasions to drug-related offenses, records show. Most recently, in 2010, he was sentenced to nine months in prison for drug trafficking.
