Iran rejected the demands of U.S. President Donald Trump to change the nuclear deal reached with Iran.

The treaty is an internationally recognized and completed pact and cannot be the subject of new discussions, the Iranian Foreign Ministry said on Saturday.

Tehran will not agree to amending and will not undertake new obligations that go beyond the framework of the treaty concluded in Vienna in 2015, the statement says.
