Vice President Joe Biden warned Sunday that the United States is watching Iran "like a hawk" to ensure compliance with the landmark nuclear deal, AFP reports.
Tehran and six world powers, including the United States, agreed to the deal in July when Iran promised to scale down its nuclear activities in return for the lifting of painful UN and Western sanctions, including on its lifeblood oil exports.
"The incentives are aligned for Iran to uphold its side of the deal. We're watching Tehran like a hawk," Biden said.
