US officials are continuing to investigate two possible cases of so-called Havana syndrome health incidents that delayed vice president Kamala Harris’s trip from Singapore to Vietnam.

The investigation was in its early stages and officials deemed it safe for Ms Harris to make her scheduled stop in Vietnam, after initially hitting pause for a few hours on Tuesday.
