Questioned in court for the first time, Bashir said that he had received $25 million from Saudi Crown Prince Mohammed bin Salman, as well as funds from other sources, but that he had not received or used the money for his own benefit.
A lawyer for Bashir said that his client denied the charges against him and that witnesses for the defense would be presented at the next hearing.
The judge denied a request for bail and said a decision on the duration of Bashir's detention would be taken at a hearing on Sept. 7.
Sudan's military ousted and arrested Bashir in April after months of protests across the country. His prosecution is seen as a test of how far military and civilian authorities now sharing power will go to counter the legacy of his 30-year rule.
