Amnesty International has called on travel platform TripAdvisor to pull out of occupied Palestine.
TripAdvisor allows travellers across the globe to browse the reviews and opinions of 8.3 million accommodations, restaurants, experiences, airlines and cruises.
However, Amnesty says TripAdvisor lists more than 70 different properties, activities and attractions in illegal Israeli settlements.
It claims that by doing this, the company is "boosting the settlement economy and contributing to settlement expansion."
It claims the promotion of settlements as a tourist destination helps to "normalise" and legitimise them to the public.
Amnesty says: "Settlements are illegal under international law - their creation amounts to a war crime.
"Settlements are on stolen Palestinian land. They should not be tourist destinations."
It has started an online petition, calling on TripAdvisor CEO Stephen Kaufer to stop listing or promoting attractions located in the settlements.
Open letter
It says it has chosen TripAdvisor as the main focus for the campaign because of its "relative importance to the tourism industry in Israeli settlements".
TripAdvisor is the most visited online tourism website by foreign visitors to Israel.
In an open letter addressed to TripAdvisor staff, Amnesty said the settlements have had a "devastating impact" on the human rights of Palestinians.
"Israel's policy of settling Israeli citizens on stolen Palestinian land in occupied territory is a war crime", Mark Dummett, head of business and human rights at Amnesty International, said.
"By promoting tourism in these illegal settlements, TripAdvisor is helping boost their economies and contributing to the immense suffering of Palestinians who have been uprooted from their land, had their homes destroyed and their natural resources plundered for settlement use".
The open letter was also shared with TripAdvisor staff.
In a recent reply to an Amnesty report, TripAdvisor said: "The listing of a property or business on TripAdvisor does not represent our endorsement of that establishment.
"We provide the listing as a platform for guests to share their genuine experiences with other travelers.
"As such, we do not remove listings of properties or businesses that remain active and open for business."
