An explosion that left six people injured and destroyed a house in Plano, Texas, on Monday was likely caused by a gas leak, officials said.

The leak was isolated to the home on Cleveland Drive, which was leveled, according to Plano Fire-Rescue. The explosion also damaged other houses, but no other homes were in danger after the blast.

Helicopter news video showed debris scattered over the neighborhood after the explosion at 4:40 p.m. Monday.

Six people were taken to hospitals — one who was inside the house that exploded and five from a home next door — the fire department said.

Three of the injured were transported to a children’s hospital, officials said. The ages of those hurt were not immediately available.
