Three men are dead and one is in a critical condition following a knife fight in Guam in the weekend.
The Nursing supervisor at Guam Memorial Hospital, Cely Mangrobang, says three men aged between 19-and-21 died in hospital from knife wounds on Saturday night.
She says a fourth stab victim, age 17, had brain surgery and is in a critical condition.
A fifth man, age 23, was treated for stab wounds to the arms, and released after treatment.
Ms Mangrobang says such incidents are uncommon in Guam.
"It's some isolated cases. Maybe they were having a brawl or a drinking spree because of the extention of the holiday but I think it escalated. They [the victims] all come from the same Micronesian Island - it won't be gang-related because if it is gang-related it should be another tribe."
Ms Mangrobang says the best way to prevent such incidents is to increase the hours of Guam's curfew regulations for minors.
