IAEA chief says Iran nuke investigation can’t continue indefinitely

The head of the United Nations' nuclear watchdog said on Monday, March 2, its investigation into Iran's atomic program could not continue indefinitely and Iran had still not provided key information, Reuters reported.

"Iran has yet to provide explanations that enable the agency to clarify two outstanding practical measures," International Atomic Energy Agency (IAEA) chief Yukiya Amano told the body's Board of Governors in Vienna.

The United States and five other powers are seeking to negotiate an agreement with Iran to curb its nuclear program in exchange for relief from economic sanctions.

Amano added that he remained seriously concerned about North Korea's nuclear program.
