US Secretary of State Antony Blinken has been grounded in Switzerland after his plane had a "critical failure" due to an oxygen leak, officials said.
America's top diplomat was due to return from the World Economic Forum in Davos when the flight issue occurred.
A separate plane was sent to fetch Mr Blinken, as his aides returned to Washington by commercial flight.
Mr Blinken has visited multiple countries since the Israel-Gaza war broke out in October.
