Twenty-five people have been killed and hundreds injured in the most violent eruption in decades in Guatemala.
The Fuego volcano, about 40km (25 miles) south-west of the capital Guatemala City, has been spewing rocks, black smoke and ash into the sky.
A river of lava hit the village of El Rodeo, killing people inside houses. The main airport in the capital, Guatemala City, has been closed.
President Jimmy Morales is considering declaring a state of emergency.
“We think that there could be a state of devastation in at least three areas,” he said.
Sergio Cabañas, head of the country’s National Disaster Management Agency (Conred), told a local radio station that a lava stream had changed course towards El Rodeo.
“Unfortunately El Rodeo was buried and we haven’t been able to reach the La Libertad village because of the lava and maybe there are people that died there too.”
This eruption is the biggest since 1974, according to local experts.
Mr Cabañas later said the dead included a member of his agency’s staff.
Several children are among those confirmed dead.
Videos published by local media show bodies lying on top of a lava flow and rescuers attending to people covered in ash.
One woman told the Diario de Centroamerica that lava had poured through corn fields and she thought more people may have died.
“Not everyone escaped, I think they were buried,” Consuelo Hernandez said.
A total of about 1.7 million people have been affected by the eruption, officials say.
