Hundreds of people opposed to Panama selling state-owned land in a duty-free zone on the Panama Canal have marched through the city of Colon a day after a violent protest resulted in a death and several injuries.
No violence has been reported in the Caribbean port city.
Heavily armed police are patrolling in response to a protest that saw people burning tires, barricading streets and throwing things at police.
Officers used tear gas and fired shots in the air to disperse the rioters.
Authorities say a 10-year-old died from a gunshot but the source of the bullet is under investigation.
People in the city object to legislation signed in to law that will let export-import businesses buy land they are now leasing in the duty-free zone.
