A partial rail service serving the Unesco World Heritage site has resumed, as have flights from nearby Cusco airport.

The political situation in the country remains volatile, though, the Foreign Office has warned. Several news wires report there being around 5,000 tourists stuck in Cusco after protesters targeted the airport.

Protests are continuing in capital Lima, as well as in other major Peruvian cities such as Arequipa and Cusco, according to the FCDO.

Entry to Lima airport is restricted to people with valid flight tickets.

Travellers are being warned to check with their airline and tour operator before attempting to travel, and to revisit their travel plans thoroughly.

Curfews remain in place for a further few days in a number of cities, and Brits have been advised to steer clear of any protests.

"Travellers arriving in Lima should be aware that travel to some parts of the country may not be possible," said the FCDO. "Protests continue to cause travel disruption, with road blockades and regional airport closures, including Arequipa, Ayacucho, and Juliaca (Puno) airports.

"Cusco airport has reopened. Lima airport is restricting entry to passengers only with valid flight tickets. Travellers should recheck with their airline and tour operator and revisit travel plans ahead of any travel."

On rail, the FCDO added: "A service from Machu Picchu has begun to resume a partial service, with travel possible some of the way before the service connects with vehicles for onward travel to Cusco."

British nationals in Peru are encouraged to complete the Peruvian tourist authority’s i-Peru form to ensure they are notified of any assistance being provided to help tourists on their way.

The unrest follows the ousting of Peruvian president Pedro Castillo. A 30-day state of emergency has been declared across Peru.
