Venezuelan opposition leader Juan Guaidó was violently blocked Sunday from presiding over a special session of congress where rivals proclaimed a substitute leader — moves opposition officials condemned as a hijacking of the country's last democratic institution.
Guaidó — whose legal challenge to the socialist government has been based on his role as head of congress — headed a small group of lawmakers trying to access the neoclassical palace where the opposition-controlled National Assembly was set to elect its leader.
As scuffles broke out, the U.S.-backed leader tried to mount an iron fence surrounding the legislature, only to be repelled again.
