More than 300 Bolivians have marched to a dusty plain near the Incachaca dam overlooking La Paz, gathering to pray for rain and an end to a severe drought that has threatened their water supply.
The 10 reservoirs that supply La Paz - one of the country's largest cities with about 2.2 million inhabitants - only contain 135 days of water combined, Bolivia's state-owned water company EPSAS has warned.
Hoisting umbrellas to stave off the heat on Friday, women wearing traditional bowler hats and colourful skirts walked alongside young men playing drums and native flutes.
Once there, they knelt, praying in Aymara, Quechua as well as Spanish, their eyes tightly closed with hands extended to the heavens.
"We have come to the summit to cry out for rain," said Susana Laruta, a member of a local evangelical Christian church.
The rainy season is due to start in December but the latest forecasts are not encouraging.
Only scarce rain is expected due to the weather phenomenon known as El Nino, the national meteorological agency has said.
El Nino, a warming of water surface temperatures in the eastern and central Pacific Ocean, is linked to extreme weather conditions.
"Climate change is what's provoking these changes," said Bernardo Vedia, a local Methodist bishop.
"That's why we've come here to join together in prayer to call out to God so that rain will fall over the earth."
