More than 60 same-sex couples are preparing to exchange vows as part of a mass wedding in Puerto Rico to celebrate a U.S. Supreme Court ruling in the socially conservative U.S. territory.

Organisers say the event will take place Sunday in San Juan’s colonial district.

Event organiser Ada Conde said Wednesday that while the majority of couples are Puerto Ricans, others from Haiti, the Dominican Republic, Cuba and Venezuela are participating.

Conde had filed a federal lawsuit seeking to have her gay marriage recognised in the U.S. territory prior to the Supreme Court decision.

Puerto Rico has since struck down laws that prohibited same-sex marriage and the recognition of such marriages.
