A Jordanian man who tried to blow up a Dallas skyscraper during an F.B.I. sting was sentenced Tuesday to 24 years in prison by Judge Barbara M. G. Lynn of Federal District Court.
The man, Hosam Maher Husein Smadi, 20, had overstayed a tourist visa, married an American woman and began dabbling in radical Islamic politics. In September 2009, undercover F.B.I. agents drew Mr. Smadi into a fake plot to blow up the 60-story Fountain Place building.
Mr. Smadi drove a truck that he believed carried an explosive device into a garage under the building and activated the false bomb, according to court documents. Facing life in prison, Mr. Smadi agreed to plead guilty to attempted use of a weapon of mass destruction in exchange for a reduced sentence.
