Mohamed Osman MohamudMohamud will appear in U.S. District Court in Portland on Monday.

"This defendant's chilling determination is a stark reminder that there are people -- even here in Oregon -- who are determined to kill Americans," said Oregon U.S. Attorney Dwight Holton. "The good work of law enforcement protected Oregonians in this case -- and we have no reason to believe there is any continuing threat arising from this case."

According to the FBI affidavit, the case began in August 2009 when Mohamud was in e-mail contact with an unindicted associate overseas who was believed to be involved in terrorist activities. In December 2009, while the unindicted associate was in a frontier province of Pakistan, Mohamud and the associate discussed the possibility of Mohamud traveling to Pakistan to participate in violent jihad.

Mohamud, a naturalized U.S. citizen living in Corvallis, was charged with attempted use of a weapon of mass destruction, which carries a maximum sentence of life in prison. A court appearance was set for Monday. Few details were available about him late Friday.

At the time, Attorney General Eric Holder said the indictments reflect a disturbing trend of recruitment efforts targeting U.S. residents to become terrorists.

Officials have been working with Muslim community leaders across the United States, particularly in Somali diasporas in Minnesota, trying to combat the radicalization.

The alleged plot in Portland follows a string of terrorist attack planning by U.S. citizens or residents.

In the Times Square plot, Faisal Shahzad allegedly tried to set off a car bomb at a bustling street corner. U.S. authorities had no intelligence about Shahzad's plot until the smoking car turned up in Manhattan.

Late last month, Farooque Ahmed, 34, of Virginia was arrested and accused of casing Washington-area subway stations in what he thought was an al-Qaida plot to bomb and kill commuters. Similar to the Portland sting, the bombing plot was a ruse conducted over the past six months by federal officials.

A year ago in another federal sting, 19-year-old Jordanian Hosam Smadi was arrested on charges he intended to bomb a downtown Dallas skyscraper. Federal officials said he placed what he believed was a car bomb outside the building but was instead a decoy device given him by an undercover FBI agent.

"I think we've been extremely lucky so far in the United States that many of the incidents have been amateur," said Bruce Hoffman, terrorism expert at Georgetown University. "But even if their skill level is not enough that they can pull off a successful attack, what is clear that the intention or motivation to cause mass homicide or destruction is certainly genuine."
