The United States has charged seven Iranians for what it said was a coordinated campaign of cyber attacks from 2011 to 2013 on several US banks and a New York dam.

At a news conference, attorney general Loretta Lynch said the seven Iranians indicted inflicted tens of millions of dollars in damages. The alleged attack against the dam by Iranians could have imposed a clear and present danger to Americans, she said.

Justice Department officials released the indictment at a news conference in Washington in what is one of the highest-profile US indictments against a foreign nation on hacking charges.
