North Korea is expected to conduct a nuclear test, its seventh such test, following the US presidential elections to be held in November, according to an official of South Korea's intelligence agency, ANI reported.

Following a briefing by the National Intelligence Service (NIS) on Thursday, Lee Seong Kweun, a member of the intelligence committee of the South Korean parliament, the National Assembly, told reporters that while a nuclear test may take place before the election, it is more likely to occur after, cited in a Yonhap news outlet report.
