Authorities in Guatemala say 18 more people have been confirmed killed by a volcanic eruption, raising the death toll to 25.

Disaster agency spokesman David de Leon said late Sunday the bodies were found in the community of San Miguel Los Lotes. Seven deaths were confirmed previously.

Rescuers have struggled to reach rural residents cut off by the eruption, which has also injured at least 20. Authorities have been unable to account for an undetermined number of people and say they fear the death toll could rise.

The Volcan de Fuego, or “volcano of fire,” exploded in a hail of ash and molten rock shortly before noon Sunday, blanketing nearby villages in heavy ash. Then it began sending lava flows down the mountain’s flank and across homes and roads around 4 p.m.
