BISMARCK, ND (AP)--State Agriculture Commissioner Roger Johnson is asking fertilizer dealers who sell ammonium nitrate and urea to report any suspicious sales of those chemicals.
Johnson said that in the wake of last week's terrorism, the FBI has asked all farm chemical officials to contact dealers in their states about the sales of nitrate and urea.
Dealers should let the FBI know if they are approached by suspicious people or if they already have sold unusual amounts of chemicals, he said.
Fire departments in North Dakota's major cities got e-mails earlier this week, warning them that emergency vehicles are subject to theft by terrorist groups. The FBI said the e-mail was started by an ambulance association as a precaution.
