A helicopter rescue team has been sent to the aid of two British pensioners stuck down a ravine in the Amazon.
The bid was launched after the couple - both in their 60s - telephoned family back home in East Sussex in a last-ditch effort to be rescued.
The couple's motorhome became trapped 200 miles south west of the city of Manaus in Brazil in a story that reinforces the need for good travel insurance.
The Britons found themselves in the situation after leaving their London home in 2008 to travel around the world, a coastguard spokesman said.
After receiving the call from their stranded relatives, the family back home in Eastbourne notified Dover Coastguard.
The case was passed on to Falmouth Coastguard, Britain's international liaison station.
Officials got in touch with the Brazilian authorities to report the incident, a Maritime and Coastguard Agency (MCA) spokesman said.
Fred Caygill of the MCA said: "It's not the first time we've assisted people across the world.
"This is a bit unusual for us as it's not of a maritime nature, but there are no boundaries in search and rescue."
