(Agence France-Presse) Recent satellite photos suggest North Korea could be preparing for fresh submarine-based ballistic missile tests, an expert on its military said Friday.

Joseph Bermudez, a specialist in North Korean defense and intelligence affairs, posted photographs on the authoritative 38 North blog of the US-Korea Institute at Johns Hopkins University which he said could show preparations for a test of a submarine-launched ballistic missile (SLBM).

“Recent commercial satellite imagery reveals several developments suggesting that North Korea may be accelerating the development of the sea-based leg of its nuclear forces,” he said.
