Hundreds of people in Ciudad Juarez, Mexico formed a "human wall" at the edge of the Rio Grande on Friday to protest President Donald Trump's proposed border wall.

The demonstrators held up flowers and colored flags reading the word "Peace" and waved to residents of the neighboring town of El Paso, Texas.

Organizers told the Associated Press that the event was meant to symbolize that uniting people was better than dividing them.

"We have, as it is being demonstrated here, many friends on the other side of the river, on the other side where they intend to build this wall that will never separate two friendly peoples," said former Mexican presidential candidate Cuauhtemoc Cardenas.

Building a border wall was one of Trump's signature campaign promises and has frayed relations with Mexico. President Enrique Peña Nieto canceled an upcoming visit after Trump's continued insistence that the U.S. would force his country to pay for the wall's construction.

Friday's protest also follows a series of massive anti-Trump rallies throughout Mexico earlier this month.
