Fault

During the meeting, the EU and the US criticised Iran for its lack of co-operation and failing to give UN inspectors full access to its nuclear sites.

Diplomats told reporters that a review read at the meeting said that Iran was using reinforced materials to build deep tunnels to protect nuclear material in case of a military attack.

The IAEA faulted Iran for starting work on the tunnel at Isfahan without informing the agency.

IAEA spokesman Mark Gwozdecky said that Iran needed to improve its openness about its nuclear activities.

So far, the US has adopted a more confrontational approach than the Europeans, threatening to have Iran referred to the UN Security Council for possible sanctions.

Talks between Europe and Iran resume in Geneva next wee

It was your fault .......

I have many faults .......... [ Here means some character faults.]

In the article, you will read 'the IAEA faulted Iran on for starting work on the tunnel at Isfahan'.
What is the meaning of this? Is the fault lies with IAEA?

The fault lies with Iran not with IAEA. I can't understand the meaning of this sentence.
