Ten people have been arrested in the United States on suspicion of spying for Russia. The Justice Department said they’d been detained in raids on Sunday. An official statement said eight of those detained were believed to be engaged on “long-term, deep-cover assignments”. Kim Ghattas reports from Washington.

It’s an espionage story with all the tools and technology of the 21st century. These ten people were arrested by the Department of Justice. It was a spy-ring. They had been here, we understand, since the early 1990s.
