Peru protests rage on despite president's plea for calm

Stone-throwing protesters fought pitched battles with police at fresh demonstrations demanding the resignation of Peruvian President Dina Boluarte, while several hundred tourists were left stranded near Machu Picchu.

Civil unrest since the ouster of Boluarte's predecessor, Pedro Castillo, in early December has left 45 people dead and prompted the government to impose a state of emergency in violence-hit areas.

Security forces fired tear gas at demonstrators using slingshots in the flashpoint southern city of Arequipa.

Crowds tried for a second consecutive day to invade an airport runway that has been closed and put under the guard of security forces.

Clashes also erupted in the northern region of La Libertad, despite a plea by Boluarte for calm.

In the capital Lima, demonstrators shouting anti-government slogans also faced off with riot police.

The airport in the popular tourist destination of Cusco reopened, prompting travellers to queue up for flights.

But rail services to the famed Machu Picchu remained suspended, leaving at least 300 people stranded in the town closest to the Inca citadel pleading to be evacuated.

In December, around 200 stranded tourists were flown out of the area by helicopter.

The protesters are trying to keep up pressure on the government, defying a state of emergency that now covers almost one-third of the country.

The violence has left 44 civilians and one police officer dead.
