Officials say natural gas is seeping through the ground from a transmission line leak near the Centreville home that reportedly exploded on Sunday, prompting evacuations of dozens of nearby houses.

The National Transportation Safety Board said the testing of pipeline infrastructure around a home in Centreville that exploded will likely last through the rest of the week.

The leak came from one of the three transmission lines running underground through the neighborhood. Crews are still working to pinpoint the source.

The search continues for a gas leak in the Centreville, Virginia, neighborhood where a house exploded Sunday night, injuring at least two people.
