North Korea’s nuclear test: your questions answered Read more

North Korea is likely to conduct its fifth nuclear test soon, possibly before its party congress in early May, a media report said on Sunday, citing South Korean government sources based on their reading of activity around the test site.

The news of signs indicating the North is readying a nuclear test comes as Pyongyang is gearing up for a ruling Workers party congress in early May, where leader Kim Jong-un is likely to boast about the program.

The likelihood of North Korea conducting a fifth nuclear test, possibly within weeks, had increased because of a failed missile launch on Friday that was an embarrassing setback for leader Kim, South Korean officials and international experts said.

“Compared to last month, the frequency of vehicle, workforce and equipment movements increased two to threefold recently,” Yonhap news agency said, quoting multiple government sources.

The possible test, if it happens, follows a fourth nuclear test in January and a long-range rocket launch in February, which led to new UN sanctions that have failed to halt Pyongyang’s weapons programmes.

South Korea’s military has said Pyongyang is technically ready for an additional nuclear test, depending on its leadership’s political decision.

The South Korean defence ministry said it could not confirm the report but reiterated that North Korea can conduct its new nuclear test at anytime.
