TAIPEI, Taiwan (AP) — A gas explosion in a residential high-rise building in northern Taiwan has killed a 1-year-old boy and injured 14 others.

The explosion shook the building shortly before noon Friday in New Taipei City. Fire department spokesman Wang Weisheng says the injured are receiving treatment in hospitals. He did not identify a cause.

The blast follows a series of underground gas explosions on July 31 in the southern city of Kaohsiung that killed 28 people and injured 286.

The investigation into the earlier blasts is focused on petrochemical firm LCY Chemical Corp. Authorities say the company did not alert the government to problems with the gas pipeline and that information could have enabled a faster evacuation of the neighborhood.
