Venezuela's socialist government installed a new head of
Congress on Sunday after armed troops blocked opposition legislators from entering parliament, in a move condemned by dozens of nations as an assault on democracy.
Troops with riot shields blocked opposition leader Juan Guaido from entering parliament for what was expected to be his re-election as head of Congress, at one point pulling him off the compound's iron railings after he tried to push past security forces.
The blockade allowed the ruling Socialist Party to hand the post to legislator Luis Parra, who was recently expelled by an opposition party over corruption allegations.
