Authorities in the US state of Arizona have agreed to remove a makeshift wall at the Mexican border following protests it is harming the environment.

The state's Republican governor, who had the barrier installed, argued that it would stem the flow of migrants crossing into America.

But critics who filed legal challenges have questioned this.

Arizona shares a 600km (370 mile) border with Mexico. Fences have been built along large stretches of it since 2017, when Donald Trump became president.
