North Korea could be preparing to launch a missile or rocket in the near future.
That's according to US radio network NPR, which said satellite images reveal an increase in activity at a facility in Sanumdong. The images taken on February 22 showed parked trucks and cars, while rail cars sit in a yard, where two cranes are erected.
This comes after recent reports showed that the Sohae satellite launch facility, which had been partially disassembled as part of disarmament steps, is back to normal operational status.
Reports said the work has picked up after North Korean leader Kim Jong-Un and US President Donald Trump's failed summit in Hanoi in February.
