Pope Francis called a meeting of experts to the Vatican to discuss the problem of forced labor and prostitution around the world and called for the church to step up in the fight against modern day slavery.

The Pope also said that organ trafficking and people smuggling were issues that needed to be eradicated.

Marcelo Sanchez Sorondo, chancellor of the Pontifical Academy of Sciences, told reporters that the pope was heavily invested in the subject of fighting slavery due to his years in Latin America. The pope had invited two experts on human trafficking that he worked with in Buenos Aires to come to the Vatican.

The group that met with the Pope released a statement saying that one of the biggest worries in Latin America is children being used by drug dealers to move product.

The group also said that the church needs to have “zero tolerance” when it comes to prostitution because it is linked to other problems like drugs and violence.
