A gas explosion ignited a massive fire at a Dallas apartment building, killing three people and prompting an ongoing search for additional missing residents, according to multiple news reports. Emergency crews responded to the scene as the blaze caused extensive structural damage to the complex.

Authorities launched search-and-rescue operations in the aftermath of the explosion, with officials indicating that the number of casualties could rise as crews worked through the debris. Displaced residents were directed to emergency shelters as investigators began working to determine the cause and origin of the gas leak that triggered the blast.

The scale of the fire required a significant deployment of firefighting resources, and the surrounding area was cordoned off as crews worked to ensure the structural integrity of remaining sections of the building. Local officials confirmed fatalities at the scene while cautioning that the full extent of the disaster remained under investigation.

Gas explosions in residential buildings can result from aging infrastructure, faulty appliances, or accidental damage to supply lines. Investigators had not publicly identified a specific cause as of the time of reporting. Utility crews were expected to assist in the assessment of the site once it was deemed safe for entry.
