Netanyahu's trial was set to resume on Sunday, after Israel lifted a state of emergency imposed over its war of aggression against Iran following Wednesday's ceasefire announcement.
"Due to classified security and diplomatic reasons connected ... to the dramatic events that have taken place in Israel and throughout the West Asia in recent times, the prime minister will not be able to testify in the proceeding for at least the next two weeks," the filing to the Jerusalem (al-Quds) District Court said, Reuters reported.
It said that a sealed envelope detailing the classified reasons was delivered to the court, which will rule once the prosecution submits its response.
Netanyahu, the first sitting Israeli prime minister to be charged with a crime, is facing charges of bribery, fraud and breach of trust brought in 2019 after years of investigations.
His trial, which began in 2020 and could lead to jail terms, has been repeatedly delayed due to his "official commitments", with no end date in sight.
