NANJING - One person died and nine others were injured, including four who sustained serious injuries, in a residential building blast in East China's Jiangsu province on Monday, local authorities said.

The explosion, which was suspected of being triggered by a leak from a household liquified natural gas bottle, happened at around 5:10 am in the village of Xi'nan in Wuxi, authorities said.

The blast destroyed a two-story building, burying 10 people.

The injured have been sent to a nearby hospital, and one died after rescue efforts failed. Four people are in critical conditions, while the other five are in non-life-threatening conditions.

Further investigation is underway.
