TEHRAN, May 30 (Xinhua) -- Iran's Foreign Ministry on Saturday condemned the recent U.S. decision to end the sanctions waivers under the 2015 Iranian nuclear deal.

The U.S. move to end the remaining sanctions waivers under the landmark deal is a "violation of United Nations Security Council Resolution 2231" which endorses the deal, Iranian Foreign Ministry Spokesman Abbas Mousavi said.

Iran will take necessary legal measures in case the U.S. decision adversely affects Iran's nuclear rights under the accord, internationally known as the Joint Comprehensive Plan of Action (JCPOA), said Mousavi.

U.S. Secretary of State Michael Pompeo announced earlier in a statement the end of sanctions waivers covering nuclear projects in Iran including the Arak reactor conversion following a final, 60-day wind-down period.
