About 10 people were sickened after a suspicious package arrived in the mailroom of an IRS building in Kansas City, Missouri, Friday morning, a fire official tells the AP. Symptoms included vomiting and sweating; two of the people were taken to a hospital but are in good condition. The package's contents have not yet been determined, but the fire department is checking for gasses and fumes. The building was not evacuated, but the package has been isolated from the public. Law enforcement is investigating, the Kansas City Star reports. (More suspicious package stories.)
