Explosions ripped through a fireworks market north of Mexico City on Tuesday, killing at least 29 people.
People in neighboring towns reported that they could feel the ground tremble beneath their feet as fireworks stalls exploded in Tultepec, about 40 kilometers (25 miles) north of Mexico City.
The series of blasts sent huge plumes of smoke billowing into the sky.
"Everything shook strongly," witness Ana Maria Alvarado told CNN Español, with her arm wrapped around a friend.
"I have a family member who works here but I have not heard from him," she said.
Seventy-two people were injured, said Eruviel Avila, governor of the State of Mexico.
Three minors are expected to be transferred to a hospital in Galveston, Texas, for treatment for extreme burns.
