At least 23 people were killed and 10 others injured after a nightclub caught fire in eastern Mexico on Tuesday night, local authorities confirmed.

The fire started at a bar in Coatzacoalcos, a port city in Mexico and the attorney general’s office said the incident could be a deliberate attack.

Eight of those killed were women and 15 were men, reported El Universal. The Mexico City-based newspaper said Molotov cocktails were believed to have been thrown at the building.

According to a statement from the Attorney general’s office,  investigations into the suspected “malicious attack” at Caballo Blanco table dancing bar are underway.
