At least seven people were killed and twenty others injured Sunday during an explosion at a resort in Playa del Carmen, Mexico, CNN reported.

Four of the dead were Canadian tourists and one minor was also killed, authorities said.

The incident was likely caused by a buildup of natural gas that somehow ignited, but the official cause is still under investigation, BBC reported.

Two Americans were among the injured and have been hospitalized, police said.
