U.S.-Iran diplomatic channel remains open, Switzerland says

GENEVA, March 2 (Reuters) - Switzerland said on Monday thatits diplomatic channel between the United States and Iran has remained active since the U.S.-Israeli air war against Iran began on February 28.

"It is available to both parties and operates in both directions," the Swiss foreign ministry said in an email to Reuters, without providing details.

Since the 1979 Islamic Revolution when Washington and Tehran cut ties, Switzerland has had a mandate of a neutral "protecting power" representing U.S. diplomatic interests in Iran.

The foreign ministry said that all its embassies in the region remained operational and that it is offering support to its nationals there seeking assistance.
