US VP Harris in Hanoi after 'Havana syndrome' delay

United States Vice President Kamala Harris landed in Vietnam Tuesday after an "anomalous health incident" in Hanoi delayed her flight from Singapore, the US embassy said, an apparent reference to the so-called "Havana syndrome" that has sickened diplomats in several countries.

"The Vice President's travelling delegation was delayed from departing Singapore because the Vice President's office was made aware of a report of a recent possible anomalous health incident in Hanoi," the US embassy statement said.
