Authorities in other parts of the island also vowed strict ban and control on use of powders and other flammable materials in public places to prevent more accidents.

Ma Xiaoguang, spokesman for the State Council Taiwan Affairs Office, expressed sympathy for the victims Sunday, and hope they all received timely and appropriate treatment.

The mainland's Association for Relations Across the Taiwan Straits (ARATS) has contacted Taiwan's Strait Exchange Foundation (SEF) to provide all possible assistance, said the spokesman.

ARATS has been actively helping the relatives of injured mainland visitors to go to Taiwan.

Fire broke out after the explosion of a large amount of flammable powder in a recreational park in Taiwan's New Taipei city Saturday evening. The park was having a Color Play Asia party attended by a total of 4,500 people, when powder ejected from a performance stage ignited, flying off in all directions and engulfing the audience.

It is the worst incidence of mass injury in the history of New Taipei city.
