PORT-AU-PRINCE, Haiti (AP) — A stampede at a mountaintop fortress popular with tourists in northern Haiti has left at least 30 people dead and several dozen others injured.

Municipal authorities in the city of Cap-Ha tien said in a statement said the stampede in Milot "resulted in numerous cases of asphyxiation, trampling and loss of consciousness." Authorities said dozens of people who attended traditional festivities at the historical site were treated at hospitals while many others were reported missing.

“According to preliminary information ... a situation of severe overcrowding, linked in particular to deficiencies in crowd management measures, triggered a stampede,” local authorities said in the statement.

Haiti’s government offered its condolences to the families of the victims of the incident at the Citadelle Laferri re.
