Chilean President Michelle Bachelet says that her government has sued Bolivia over a water dispute at the International Court of Justice.
Bolivian President Evo Morales said earlier this year that his country would sue Chile in the Netherlands-based court seeking to force it to pay compensation for using the Silala river in a border region.
Yesterday, Bachelet said that Bolivia is claiming ownership over shared water resources and that the Silala flows into Chile by the law of gravity. She says Bolivia has long recognised the Silala as an international river.
In 2013, landlocked Bolivia asked the international court to order Chile to negotiate over Bolivia's claim for access to the Pacific. The case is being heard by the court, whose rulings are final and binding.
