U.N. peacekeepers clashed with Haitian demonstrators Thursday who were protesting the deaths of migrants being smuggled into the Dominican Republic earlier this week.
At least one person was killed and several others wounded in the border clash that came as the Dominican Republic said it had buried 24 of the migrants killed in Tuesday's incident.
Officials said another migrant died Thursday in a hospital, bringing the death toll to 25.
The dead were among 50 migrants hidden in the back of a truck that fled Tuesday when detected by border police.
Some witnesses say the victims suffocated and others that they jumped, or were thrown, from the speeding truck.
The truck driver is in custody and Dominican officials have pledged to conduct a complete investigation.
