TEHRAN, June 29 (Xinhua) -- A senior Iranian official said Iran will overcome the new wave of sanction pressures by the U.S., Tasnim news agency reported Friday.

"The American officials believe that Iran would surrender under the pressure of sanctions, but it will become obvious soon that the Iranian nation will successfully overcome the challenge of new sanctions," Ali Akbar Velayati, a senior adviser to Iran's Supreme Leader Ayatollah Ali Khamenei, said in the northeastern city of Mashhad.

"Today, the region's top power is undoubtedly Iran, which has been able to cut off the hands of the United States and its regional allies from the set (of pro-resistance countries) around us," the Iranian former foreign minister said.

Velayati described the U.S. anti-Iran sanctions as "a kind of revenge," stressing that the Iranian government and nation will stand together in confronting the sanctions.

The U.S. Secretary of State Mike Pompeo said last month that Iran will suffer the toughest sanctions in history from the United States if it does not change the current course.

Pompeo urged Tehran to report to the International Atomic Energy Agency about its nuclear program, end proliferation of its missiles, and stop supporting "terrorist groups" in the Middle East.
