Opposition leader and Nobel laureate María Corina Machado reappeared in Venezuela Sunday for the first time since December, returning from exile at a time when doubts about the country's democratic future — and the role of the U.S. — are growing.

It was her first appearance since the U.S. military deposed the country's then-President Nicolás Maduro in January, replacing him with an interim president who has exceeded the time she was authorized to serve, with no election scheduled.

Brazil's President Luiz Inácio Lula da Silva, a vocal critic of U.S. President Donald Trump, was reelected Sunday in a result that provides relief to critics of widening U.S. influence in Latin America.

With 100% of the vote counted, Brazil's electoral court announced that the soon to be 81-year-old Lula had a lead of nearly 4.4 million votes over opponent Flávio Bolsonaro, giving him 51.8% of the total vote. Bolsonaro quickly refused to concede defeat and asked for the election results to be annulled after an evening of chaos at some polling places that followed a last-minute decision to extend voting by two hours.

Ukrainian President Volodymyr Zelensky on Sunday said that a trilateral meeting between Kyiv, Washington and Moscow would take place in November aiming to restart stalled peace talks.

"We are ready to talk. If it's a territorial issue, it must be addressed at a leadership level. Other issues fall within the remit of the technical groups. All this can therefore be discussed in November," Zelensky said in an interview with Ukrainian television.

U.S. President Donald Trump has bristled when asked how far he was from a possible attack on Iran. He recently said on social media he would not hit Iran again before the Nov. 3 midterm elections.

“Do you really think I’m going to tell you if I’m going to do it?" Trump responded. “And there’s a possibility I will. There’s also a possibility we’ll have a nice, big, beautiful agreement.”

Iran's Foreign Minister Abbas Araghchi said on Sunday that a potential resumption of war with Israel and the United States would not change his country's positions.

The remarks come amid mounting U.S. and Israeli threats of renewed attacks on Iran, as President Donald Trump said on Friday that Washington "may do another little Epic Fury," referring to the U.S.-Israeli campaign on Iran that began on February 28.

Iran's judiciary said that its chief held a rare meeting with the country's supreme leader Mojtaba Khamenei, who has yet to appear in public since being appointed.

Mojtaba was chosen in March to succeed his father and longtime ruler Ayatollah Ali Khamenei, who was killed in U.S.-Israeli strikes in central Tehran alongside senior military commanders at the start of the Middle East war, and was said to have been injured in the same attack.

Iranian President Masoud Pezeshkian said that many Iranians were struggling to put food on the table, as the economic pressure from the Middle East war with the United States mounts.

The United States appears to be preparing to resume large-scale strikes against Iran, but there is unlikely to be a military solution for either side in the devastating conflict, experts say.

The United States could strike Iran as soon as this weekend, a U.S. envoy said, after mounting threats by both Washington and Israel.

Iran has "substantially increased" its efforts to target Americans in the Middle East and beyond, U.S. national intelligence chief Jay Clayton has warned.
