A teacher has been killed and multiple pupils injured in a school shooting in Thailand, authorities said.

The shooting happened at the Debsirin Nonthaburi School in the Bang Kruai district of Nonthaburi province, located right next to Bangkok.

It remained an active scene for several minutes as the suspected gunman remained on the school campus while police responded to the scene.

The Royal Thai police later said the suspected gunman was dead, without confirming whether he was shot by the police.
