LONDON — The International Atomic Energy Agency will report that Egypt failed to report nuclear tests required under the Nuclear Non-Proliferation Treaty.
The IAEA has drafted a report that determined that Egypt repeatedly failed to report nuclear materials and activities over the last 15 years, agency sources said. The sources said that the agency said in the report that this was a “matter of concern,” but did not recommend sanctions.
