CLEVELAND -- A federal grand jury has indicted three Ohio men on charges of planning attacks on U.S. military personnel in Iraq, according to an indictment.

The three men, who all lived in Toledo within the last year, were arrested over the weekend, said Assistant U.S. Attorney David Bauer in Toledo. The indictment was unsealed Monday.

They were to be arraigned in federal courts in Cleveland and Toledo on Tuesday afternoon.

U.S. Attorney General Alberto Gonzalez spoke to reporters Tuesday in Toledo about the indictments, but wouldn't comment about the case outside of the facts presented in the court documents.

He did say that the men accused are alleged to have had the "motivation" and the "means" to carry out their tyhreats and that the Justice Deptartment had a "strong case" to prosecute.

Gonzalez would not say whether the warrantless wiretaps were used to help in the investigation against the men. The wiretaps have come under criticism from leaders of both major political parties because of worries that they violate frederal laws that protect privacy.

According to court documents, the suspects recruited others to train for a violent holy war against the United States and its allies in Iraq, the indictment said. The group traveled together to a shooting range to practice shooting guns and studied how to make explosives, the indictment said.

The indictment alleges that one of the men, Mohammad Zaki Amawi, twice threatened to kill or inflict bodily harm against President George W. Bush while speaking with others.

Prosecutors said the plot began in November 2004.

Amawi is a citizen of Jordan and the United States. The others are Marwan Othman El-Hindi, a U.S. citizen born in Jordan; and Wassim I. Mazloum, who came to the U.S. from Lebanon in 2000. Mazloum operated a car business in Toledo with his brother.
