A press conference by Maria Corina Machado - the Nobel Peace Prize laureate, who is currently in-hiding - was cancelled on Tuesday, with the Nobel Institute saying they are "in the dark" about her whereabouts, BBC reported.

Machado is Venezuela's opposition leader and has been in hiding since the country's disputed 2024 election, which she and her supporters say was stolen.

She was awarded the Nobel Peace Prize for efforts to bring democracy to Venezuela, and was expected to formally collect it in a ceremony on Wednesday, according to BBC.
