Tensions Rise as Venezuela Threatens Guyana's Oil-Rich Region

South American countries, including members of the regional bloc Mercosur, have called for a peaceful resolution to the border dispute between Guyana and Venezuela. Tensions have escalated after a referendum in Venezuela supported the annexation of the oil-rich region of Essequibo, which is controlled by Guyana. Brazil has expressed growing concern and increased its military presence in the border region. The United States has pledged unwavering support for Guyana's sovereignty and announced joint military flight exercises. The International Court of Justice is currently considering the border dispute, and Venezuela has been ordered to refrain from taking action in Essequibo.
