Border walls have been stirring international debate in the last two years, with U.S. President Donald Trump declaring his intent to build one between the United States and Mexico. But another wall in Latin America is also drawing debate.
In March of 2017, Ecuador began construction of an 800-meter long concrete barrier along part of its border with Peru. It is four meters high and stands between the towns of Huaquillas to the south, and Aguas Verdes to the north.
Ecuador claims the wall is part of an urban renewal project, to include a lineal park. Peru says it violates a peace agreement reached by both countries after their 1995 armed conflict. And even though Ecuador has halted construction, controversy still abounds. Correspondent Dan Collyns visited both sides of the frontier to explore what might happen next.
