HANOVER, Md. – Two packages sent to state government buildings 20 miles apart released smoke and the smell of sulfur when they were opened Thursday, officials said. A mailroom employee was hurt, but not seriously.

State officials initially said the packages exploded, but later said there were no blasts.

State police spokesman Greg Shipley said mailrooms at state offices across Maryland were being quarantined until it could be determined if any other packages had been sent.
