SEOUL (Reuters) -North Korea's Kim Yo Jong, sister of leader Kim Jong Un, said on Monday that the United States should avoid any "foolish act" that could put its security at risk and rejected offers of talks as a ploy, state news agency KCNA reported.

Kim made her comments after White House national security adviser Jake Sullivan said the United States remained concerned that North Korea would carry out another intercontinental ballistic missile (ICBM) test, after it last week fired an ICBM off its east coast.
