The U.S. State Department has issued a travel alert for U.S. citizens to be advised of unstable "social and security situations" in several areas in Bolivia.
A U.S. statement Thursday said local groups and other factions in the regions of Potosi, Oruro and Uyuni have been protesting against the Bolivian government about a border dispute, as well as accusations that officials have not carried out development projects in those regions.
The statement said protesters have erected roadblocks that have trapped thousands of people, including several hundred tourists, for up to 16 days. It said food, water and medical supplies in Potosi, Oruro and Uyuni are limited.
The State Department urged U.S. citizens in Bolivia to avoid traveling to those three regions until the situation is revolved.
