At least two people have died during large-scale celebrations in Mexico City after the country’s national football team advanced to the knockout stage of the FIFA World Cup.

The Mexico City government said on Wednesday that a 19-year-old woman and a 44-year-old man died from asphyxiation during the celebrations.

Authorities had not confirmed local media reports of a third fatality as of the time of reporting.

The celebrations erupted after Mexico defeated Ecuador to secure its first World Cup knockout-stage qualification since 1986, earning a place in the round of 16.

According to the city government, more than one million people gathered across the capital, with the largest crowds converging around the Angel of Independence monument.

Authorities have not provided further details on the circumstances surrounding the deaths or whether additional safety measures will be introduced for future public celebrations.
