Bazilian President Jair Bolsonaro said his government was working to avoid violence after supporters of Venezuelan opposition leader Juan Guaido gained access to the country’s embassy in Brasilia on Wednesday. The move led to a standoff with backers of Venezuelan President Nicolas Maduro and scuffles outside the embassy, creating a diplomatic embarrassment as the BRICS summit of major emerging economies kicked off in the Brazilian capital. Tensions at the embassy highlight the stark differences between Bolsonaro, who has recognised Guaido as Venezuela’s leader, and Maduro’s Chinese and Russian allies, who are joining presidents from India and South Africa in Brasilia this week. Venezuelan embassies around the world have become flash points for the competing claims of Guaido, the head of Venezuela’s National Assembly, and Maduro, a socialist who took over from late President Hugo Chavez in 2013.
