Tehran: Iran's supreme leader, Ayatollah Ali Khamenei, said on Friday that the US is Tehran's "enemy" and should not be trusted.
Despite Iran's fulfilment of its obligations pertaining to the nuclear deal, the US has failed to live up to its commitments, Khamenei said.
"If any political trend (group) trusts the US, it will commit a grave mistake," he said.
Khamenei made the remarks in a ceremony held to commemorate the 27th death anniversary of the founder of the Islamic republic, Ayatollah Ruhollah Khomeini, Xinhua news agency reported.
The ceremony was held at Khomeini's mausoleum in southern Tehran with the attendance of high-ranking officials and foreign diplomats and guests.
