About 70 other people were injured in the explosion that took place around noon in the village of Kaungtup, in Namhkam township.
The area, located about 3 kilometers (2 miles) south of the Chinese border, is under the control of the Ta’ang National Liberation Army, an ethnic armed group fighting Myanmar’s central government.
A rescue worker who rushed to the site of the blast told The Associated Press that 46 bodies, including six children, had been recovered by Sunday evening and taken for cremation.
The rescuer, who spoke on condition of anonymity for security reasons, said 74 wounded people had been transported to the township hospital and rescue operations were continuing.
Another rescuer in Namhkam, who also spoke on condition of anonymity, said about 40 people were killed and more than 100 houses near the blast site were damaged.
