One firefighter was killed — and at least nine other firefighters and two civilians injured — in a large home explosion in Northern Virginia's Loudoun County Friday night, officials said.

In a news briefing late Friday night, Loudoun County Fire and Rescue Assistant Chief of Operations James Williams said that fire crews were first called to the home in the community of Sterling at about 7:40 p.m. local time.

Soon after firefighters arrived, an explosion occurred, Williams said.
