National Guard vehicle is seen ramming into van of Guaido rebels

Venezuelan opposition leader Juan Guaido has urged protesters and soldiers back on to the streets for May Day demonstrations against Nicolas Maduro as he attempts to topple the President from power.



Guaido promised the 'largest march' in Venezuela's history as he branded Maduro 'a tyrant who locks himself away in fear' in a videotaped rallying cry posted on Twitter overnight Tuesday.



It comes after his 'military uprising' against Maduro descend into violence on the streets of Caracas with live rounds and tear gas fired, molotov cocktails thrown, and demonstrators run over by an armoured car.



Demonstrators also took to the streets in other cities, with at least one person, a 24-year-old, killed in the central state of Aragua. More than 100 were injured around the country.



Guaido and Maduro are locked in a battle for control of the military, which will be key to deciding Venezuela's future. While Guaido claimed he is 'the legitimate commander of the armed forces' in his video, Maduro used his his own TV address to insist that he retains control of the troops.



Guaido, who has the backing of the US and western governments, is trying to wrest control of Venezuela away from Maduro, whose rule has seen the country descend from one of the wealthiest in South America into poverty.
