UN's Secretary General has warned Venezuela's authorities not to use deadly force against demonstrators following the opposition leader Juan (WAN) Guaido’s calls for protests against President Nicolas Maduro.

Antonio Guterres spoke to Venezuela's Foreign Minister Jorge (YOR-GAY) Arreaza late Tuesday and UN spokesman Stephane Dujarric said UN officials have had contacts with aides to Guaido.

This comes after clashes left dozens injured on Tuesday with thousands of marchers continuing their protests on Wednesday amid rising geopolitical tensions surrounding the nation’s leadership.
