In Arizona, a human rights activist from the group No More Deaths went on trial Monday for leaving plastic jugs of water in a National Wildlife Refuge near the US-Mexico border. The activist, Walt Staton, says the water jugs were left to prevent migrants from dying of dehydration. The US government has accused Staton of “knowingly littering” in the Buenos Aires Wildlife Refuge. The group No More Deaths has worked for years to provide humanitarian aid to migrants. Over the past decade, nearly 2,000 men, women and children have died while trying to cross the border into Arizona.
