There were chaotic scenes in Honduras on Friday after a gas cylinder exploded at a busy marketplace, injuring more than 70 people, including children and the elderly.

Stall owners and shoppers at the market in Tegucigalpa suffered from second- and third-degree burns after the cylinder exploded at a kitchen on the site, the Honduran daily La Prensa said.

Honduran Health Minister Yolani Batres called a news conference in the capital to update the public on the number of injured.

"A total of 72 people were treated. From these 72 patients eight are children and they're being attended to at the University School Hospital, 52 of them are adults. Hospitalized here are 39 [adults]," she said.

No deaths have been reported, but local media have called for people to come forward to donate blood.

Investigations into the incident are ongoing with the cause of the explosion still to be identified.
