Hong Kong  - Seven people have been treated in hospital for burns suffered during Hong Kong's Mid-Autumn Festival celebrations, police said Monday.

A 16-year-old boy and an 11-year-old boy were still in hospital while five other patients aged five to 53 were treated and discharged, a police spokesman said.

People across the city of 6.9 million joined in outdoor parties where children burned candles and lanterns and watched the full moon Sunday evening.

The Mid-Autumn festival, or moon festival, dates back 3,000 years and is the second most important festival in the Chinese calendar after the Lunar New Year holiday. (dpa)
