After Juan Guaidó said rebellion was at hand, supporters clashed with loyalists to the president. By day’s end, Mr. Guaidó fell short of the prize he sought.
It was the boldest move yet by Juan Guaidó, Venezuela’s opposition leader: at sunrise, he stood flanked by soldiers at an air force base in the heart of the capital, saying rebellion was at hand.
Mutinous security forces supporting him had released the country’s most famed political prisoner. National guardsmen stood at Mr. Guaidó’s side as others joined marches to support the protesters that they had spent years repressing.
In the streets, anti-government demonstrators clashed with forces loyal to the president amid reports of live fire, rubber bullets and tear gas. A health clinic in Caracas took in 69 people injured during the day. An armored vehicle rammed protesters, but it was not immediately clear how many people were hurt.

While the highest ranks of the military dig into their support for Mr. Maduro’s government, many rank-and-file soldiers appear willing to defy their commanders and come to the aid of the opposition.
“I think ultimately what we’re going to see coming out of this is both the government and the opposition recognizing that their hands were not as strong as they thought they were,” said Geoff Ramsey, an analyst at the Washington Office on Latin America, a human rights group.
The gamble by Mr. Guaidó was brazen: A predawn takeover of a military base in the heart of the capital, Caracas. The deep symbolism of such an act, it was hoped, would help galvanize soldier and citizen alike to end Mr. Maduro’s authoritarian rule.
The Trump administration immediately came out in support of the opposition, with the president, vice president and others publicly stating their approval on Twitter. President Trump also threatened “a full and complete” embargo on Cuba if it did not stop what he called “military and other operations for the purpose of causing death and destruction to the Constitution of Venezuela.”
The Trump administration, which has backed Mr. Guaidó since he first challenged Mr. Maduro’s authority more than three months ago, clearly thought the day would unfold differently.
Secretary of State Mike Pompeo, speaking on CNN’s “State of the Union,” said Mr.
