The explosion occurred at the dry fish section of the park.
In the confusion that ensued, two persons were severely injured, while scores, mostly women, suffered various degrees of injuries. The injured have been rushed to a nearby hospital.
It could not be immediately ascertained what could have led to the explosion or those behind it.
