Nine people were killed when their bus was swept away by floodwaters from the Tres Quebradas River in eastern Guatemala, officials said Wednesday.

Nine bodies have been recovered and the search continues for seven other passengers listed as missing, the spokesman for the Conred emergency management agency, David de Leon, told reporters in the capital.

The tragedy occurred Tuesday night when the bus driver tried to cross the rain-swollen river, fire rescue personnel told radio stations.

One of the victims was identified as Elba Flores, who volunteered as a nurse at a clinic in the town of Olopa.

Torrential rains also caused flooding in the southern coastal town of San Sebastian, but there were no reports of casualties, De Leon said, though seven homes were destroyed and 100 others damaged.

Heavy rains and flooding are blamed for more than 30 deaths this year in Guatemala.
