KANSAS CITY, Mo. (AP) — Cadaver dogs searched through the smoldering rubble of a Kansas City restaurant after a gas explosion sparked a massive blaze Tuesday evening in an upscale shopping district.

More than a dozen people were injured in the blast and resulting fire, which occurred just after 6 p.m. and completely destroyed JJ’s restaurant. There were no reports of fatalities by Tuesday night, though authorities cautioned that could change because it was unclear how many people were inside at the time of the blast.

Kansas City Fire Chief Paul Berardi said cadaver dogs were called to the scene because of the size of the conflagration.
