An explosion and fire destroyed a Corpus Christi home, injuring three people, and shattering windows on nearby houses up to three blocks away.

Corpus Christi Fire Department crews were called at around 5:30 a.m. that an explosion had taken place at Holmes Drive according to Caller.com.

"As a safety precaution power in that area is off as the fire department investigates the source of the explosion," said Andy Heines, AEP Texas spokesman. "As of 11:30 a.m. we've been told because of the investigation, power to those homes may not be restored until Saturday or Sunday."

At least two of the three injured individuals were taken to Christus Spohn Hospital Memorial by ambulance in critical condition. The two men were later flown to the San Antonio Military Medical Center's burn unit.

A third person was treated for injuries at the scene but refused to be transported to a hospital according to the Associated Press.

The explosion is still under investigation as of press time.

The gas department is currently checking the lines, meters and valves to see if there was any kind of release according to Fire Chief Andy Cardiel.

"It's going to be way too early to determine what a cause is at this point," Cardiel said in a press statement.

At least 20 homes lost power due to the explosion as well according to the Associated Press.
