'Deadly plot by Iranians to kill Saudi ambassador'

The US says it has broken up a major terror plot in which agents linked to Iran sought to assassinate the Saudi ambassador in Washington.

Two men originally from Iran - one a naturalised US citizen - have been charged with counts of conspiracy, Attorney General Eric Holder said.

The plot was "conceived" in Iran by the Quds force, part of Iran's Revolutionary Guard Corps, he added.
