VIENNA, Feb. 19 (Xinhua) -- The UN nuclear agency, the International Atomic Energy Agency (IAEA), has made no major progress in verifying outstanding issues related to Iran's alleged nuclear weapons program, according to an official report on Thursday.

The confidential report obtained by Xinhua revealed that the IAEA has yet to receive information from Tehran on two outstanding issues related to the alleged nuclear bomb research, the so-called "possible military dimensions (PMDs)," which Iran denies.

"Iran has not provided any explanations that enable the Agency to clarify the two outstanding practical measures," the report said.

"These measures are related to the initiation of high explosives and to neutron transport calculations," the report noted. Enditem
