Two children have died in a house fire, authorities in Clovis said.

The blaze was first reported shortly after 9:30 a.m. Wednesday, Clovis police spokesperson Capt. Robbie Telles said.

Responding officers found flames coming from the bottom floor of the home. Telles said they tried to enter once they learned two children were inside. There was too much fire and smoke, he said. Officers couldn't make it past the front door.

Clovis firefighters then arrived and put out the fire within minutes.
