North Koreans are feeling insecure about infrastructure damage caused by the reclusive country's latest nuclear test but remain indifferent to its outcome, U.S.-based media Radio Free Asia said Sunday, citing Japanese media outlet Asia Press.

A resident in Ryanggang Province bordering China told Asia Press that a number of apartments located some 150 kilometers away from the Punggye-ri nuclear test site in the country's northeastern region developed cracks following North Korea's fifth nuclear test earlier this month, according to the report.

Still, many North Korean residents remain unconcerned about the regime's nuclear or submarine-launched ballistic missile tests, the resident was cited by RFA as saying.

Jiro Ishimaru, the Osaka bureau chief of Asia Press, said North Korea's efforts to propagandize the latest nuclear test as the achievement of its leader Kim Jong-un are unlikely to have a significant effect, as its people are suffering economically.

On Sept. 9, North Korea detonated another nuclear device despite the international community's calls for the denuclearization of the Korean Peninsula. In January, North Korea conducted its fourth nuclear test after its previous tests in 2006, 2009 and 2013. (Yonhap)
