BBC: Iran remains the "most active state sponsor of terrorism" in the world, a report by the US state department says.
It says Iran's role in the planning and financing of terror-related activities in the Middle East and Afghanistan threatens efforts to promote peace.
Al-Qaeda, however, remains the biggest danger to the US and the West, the annual report states.
It says that while the number of terror attack around the world is dropping, they are on the increase in Pakistan.
'Existential threat'
The new US administration may be trying to engage Tehran, but, just like last year, Iran is still described as the most active state sponsor of terrorism. >>> By Kim Ghattas | Thursday, April 30, 2009
