CARACAS, Venezuela — Venezuelan President Nicolás Maduro was sworn in Friday for a new term, extending his increasingly repressive rule in the face of renewed protests and rebukes from the United States and others who believe he stole last year’s vote.

Venezuela’s legislative palace, where he was sworn in and delivered a fiery speech, was heavily guarded by security forces who have become Maduro’s main hold on power since last summer’s disputed election. Maduro, likening himself to a biblical David fighting Goliath, accused his opponents and their supporters in the U.S. of trying to turn his inauguration into a “world war.” He said his enemies’ failure to block his inauguration to a third six-year term was “a great victory” for Venezuela’s peace and national sovereignty.

A day before hundreds took to the streets to protest Maduro’s power grab. It was relatively calm but after it ended, aides to the popular former lawmaker María Corina Machado — the driving force behind what’s left of Venezuela’s beleaguered opposition — said she was briefly detained by security forces.
