Recent satellite imagery has revealed two, yet unidentified, underground facilities near a North Korean nuclear complex. It has been speculated by the international community for quite some that North Korea had underground facilities like the one which has been discovered, and the latest satellite images offer proof of the same.

Tunnel entrances and soil piles have been identified in the images which were of the Yongbyon Nuclear Scientific Research Center, which is almost 60 miles to the north of Pyongyang.

While it is not possible to exactly pinpoint the purpose of these underground facilities, their location within the nuclear complex and subsequent attempts to qualify them to suggest that these could be uranium enrichment facilities.

"While it is impossible to remotely discern their purposes, their location within Yongbyon’s security perimeter and subsequent camouflaging qualify them as subjects of interest for future inspection teams," analysts with North Korean website 38 North said in their report.

One such enrichment facility had already been declared at Yongbyon, which provided nuclear material for six weapon tests that were carried out during the Kim Jong Un’s facility, but experts have been suggesting more could be present.

The speculations began back in 2013 when a North Korean defector claimed such facilities existed for the purpose of hiding of materials and laboratory testing equipment and important systems during inspection from International Atomic Energy Agency (IAEA).

The images have come at a time when uncertainty hung over nuclear talks between the U.S. and North Korea.

"We’ll see what happens. It might work out, it might not work out. I’m not saying it will. But in the meantime, he hasn’t been testing any nuclear," President Donald Trump said regarding his negotiations with Kim.
