On Monday, a spokesman for Iran’s nuclear agency, Behrouz Kamalvandi, said that the Islamic Republic would break its uranium-stockpile limit set by the nuclear deal in the next 10 days unless European powers are able to save the agreement, which the United States pulled out of in May 2018.

“We have quadrupled the rate of enrichment and even increased it more recently, so that in 10 days it will bypass the 300-kilogram [660-pound] limit,” Kamalvandi said on state TV. “There is still time … if European countries act.”

According to Kamalvandi, Iran would increase its uranium enrichment levels “based on the country’s needs.”

This increase could be to any level past the 3.67 percent set by the nuclear deal. Iran needs 5 percent enrichment for its nuclear power plant in Bushehr, as well as 20 percent for a research reactor near Tehran, said Kamalvandi.

The latest development comes in the wake of attacks on oil tankers last week in the Gulf of Oman. The United States has blamed Iran for the attack.
