Iran’s legislative watchdog council approved a bill on Wednesday that would ramp up the country’s uranium enrichment to near weapons-grade levels and suspend access to any of its nuclear facilities if U.S. sanctions against the country are not lifted early in President-elect Joe Biden’s first term.

The bill, passed by the Iran Parliament on Tuesday, orders Iran’s atomic energy agency to return uranium enrichment to levels not seen in the country since the United States and Iran entered the Joint Comprehensive Plan of Action in 2015, commonly referred to as the Iran nuclear deal, if the incoming Biden administration and European powers fail to lift sanctions by early February, according to the New York Times.
