Yellen: $6 Billion in Iranian Funds Could Be Refrozen Amid Tensions Over Oil Revenue and Hamas Attack

Treasury Secretary Janet Yellen said $6 billion in Iranian oil revenue held in Qatar could potentially be refrozen.

The funds were released to Iran as part of a prisoner exchange deal in September.

Some officials say there is a link between Iran and a recent Hamas attack on Israel.

The Biden administration says the funds were for humanitarian purposes only.

Yellen said the U.S. has not relaxed sanctions on Iranian oil.
