Israel's premier says the coming month will be "critical" for preventing a nuclear deal with Iran.

Prime Minister Benjamin Netanyahu said Sunday that the U.S. Congress may be the body that influences the emerging deal between world powers and Iran. He said he will travel to Washington to explain why the deal is "dangerous to Israel, dangerous to the region and dangerous to the world."

Netanyahu's vehement opposition to compromising with Iran over its nuclear program has further stressed his relationship with U.S. President Barack Obama. The White House is considering ways of undercutting the upcoming visit. Several members of Congress have said they will boycott Netanyahu's address.

Netanyahu has warned a bad deal with Iran will allow it to build nuclear weapons that it could use to threaten Israel.
