Native American burial sites in Arizona have been blown up by construction crews building the US-Mexico border wall, according to lawmakers and tribal leaders.
Authorities confirmed that “controlled blasting” has begun in Organ Pipe Cactus National Monument, a Unesco recognised natural reserve about 185 km west of Tucson, the BBC said in a report on Tuesday.
The UN had designated Organ Pipe, also known as Monument Hill, as an International Biosphere Reserve in 1976, calling it “a pristine example of an intact Sonoran Desert ecosystem”.
