GUATEMALA CITY, Guatemala —  A 330-foot-deep sinkhole killed at least two teenagers as it swallowed about a dozen homes early Friday and forced the evacuation of nearly 1,000 people in a crowded Guatemala City neighborhood.

Officials blamed the sinkhole on recent rains and an underground sewage flow from a ruptured main.

The pit emitted foul odors, loud noises and tremors, shaking the surrounding ground. A rush of water could be heard from its depths, and authorities feared it could widen or others could open up.

Rescue operations were on hold until a firefighter, suspended from a cable, could take video and photos above the hole and officials could use the documentation to decide how to proceed.

The dead were identified as Irma and David Soyos, emergency spokesman Juan Carlos Bolanos said. Their bodies were found near the sinkhole, floating in a river of sewage.

Their father, Domingo, was still missing, according to disaster coordinator Hugo Hernandez.
