Relatives of 10 workers trapped in a flooded coal mine in northern Mexico clung to hope they were still alive Friday, nearly 48 hours after a cave-in sparked a major rescue operation.
Family members spent a second night waiting anxiously for news after the latest disaster to strike Mexico's main coal-producing region in Coahuila state.
"I feel desperate, not knowing what's happening and when I'll see him again," said Jesus Mireles Romo, whose father was among the missing.
"But I have faith that it will turn out well, that they will all get out," he told AFP, his eyes red from crying.
The 24-year-old rushed to the mine in Agujita in the municipality of Sabinas with his two brothers on Wednesday to try to help the victims before the authorities took over, and has not left since.

"It's painful to see your children who don't lose hope of seeing their father again," said his mother Claudia Romo, 45.
Five miners managed to escape in the initial aftermath of the cave-in Wednesday, but since then no survivors have been found.
Around 230 army and other government personnel were sent to the site, about 1,130 kilometers (700 miles) north of Mexico City, the defense ministry said.
Soldiers and emergency workers worked through the night under floodlights pumping out water from the mine to try to make it safe enough to enter.
Authorities said the three mine shafts descended 60 meters (200 feet) and the floodwater inside was 30 meters deep -- slightly lower than the day before.
"It's essential to reduce the water level ... to allow the safe entry of specialized search and rescue personnel," civil defense national coordinator Laura Velazquez said.
"We're working tirelessly to rescue the 10 trapped miners," she said.
Family members cried and comforted each other while hopes of finding survivors dimmed with each passing hour.
"What we want is for them to retrieve the bodies," Angelica Montelongo said with a sad and tired look, before summoning up new hope that her brother Jaime would be rescued.
"But hey, God willing, right? You have to have faith that they're alive," she said.
Experts and relatives painted a picture of a precarious profession fraught with risks extracting coal from the mines with lax safety standards.
"There's always job insecurity... and danger," said Blasa Maribel Navarro, whose cousin Sergio Cruz has mined coal for several years to support his two daughters.
Navarro said she was still hopeful of seeing him alive "because we trust in God."
History of accidents
Crudely constructed mines like the one that collapsed lack concrete reinforcements to protect workers from a cave-in, engineering expert Guillermo Iglesias said.
The miners "dig a shaft two meters in circumference and keep digging until they reach a small layer of coal," he told local radio.
The only thing supporting the surrounding earth is usually a large plastic tube through which the workers enter, he added.
Coahuila's state government said the miners had been carrying out excavation work when they hit an adjoining area full of water, causing the shaft to collapse and flood.
Coahuila has seen a series of fatal mining accidents over the years.
Last year, seven miners died when they were trapped in the region.
The worst accident was an explosion that claimed 65 lives at the Pasta de Conchos mine in 2006.
Only two bodies were retrieved after that tragedy and the families have repeatedly urged the Mexican authorities to recover them.
