Iran's Foreign Ministry on Saturday dismissed recent anti-Iran remarks by US President Barack Obama as "baseless," Tasnim news agency reported.

Military threats against Iran are in contradiction to the UN Charter, and would bring about international liability for the US administration, Iran's Foreign Ministry Spokeswoman Merzieh Afkham was quoted as saying on Saturday.

In a letter to Jerrold Nadler, a Democrat in the House of Representatives, Jerrold Nadler, Obama said the United States will keep military options open if Tehran fails to honor its commitments relating to the recent nuclear deal with the world powers aimed at curbing its nuclear program.

Such "repetitive" claims by the US officials against Iran are in line with the interests of Israel, not in the US' interests, Afkham was quoted as saying.

She deplored the US supports for the Israel, saying that Israel is the main source of instability and terrorism in the Middle East.
