Sudanese President Omar al-Bashir has admitted receiving 90 million dollars in cash from Saudi Crown Prince Mohammed bin Salman, an investigator said at his trial in Khartoum on Monday.

The police team, Ahmed Ali, said at the start of the trial of al-Bashir on charges of corruption, that the former president told him that the money "handed over a number of delegates from Mohammed bin Salman."

Bashir, who ruled Sudan for 30 years, arrived at the court in Khartoum, where his trial began on charges of corruption.

The AFP news agency quoted its correspondent from the Institute of Judicial and Legal Sciences - where the trial is taking place - as saying that Bashir arrived amid heavy military guard.

In April, the head of the junta, Abdul Fattah al-Burhan, announced that $ 113 million worth of banknotes had been found in three different currencies at al-Bashir's residence in Khartoum.

In May the prosecutor also announced that Bashir had been charged with killing protesters in protests that toppled him.

Bashir, 75, who was forced to step down on April 11 after months of demonstrations against his regime, appeared before the public prosecutor for the first time on June 16.

The trial of al-Bashir was scheduled for Saturday, but was postponed to coincide with the signing ceremony of the final agreement on the transition between the junta and the forces of the "Declaration of Freedom and Change" leader of the popular movement.

On July 31, the Sudanese judiciary postponed Bashir's trial for the first time for "security reasons" he did not explain.

Demonstrations against Bashir's rule erupted on December 19, after his government tripled the price of bread.

The Hague-based International Criminal Court (ICC) has indicted Bashir, including war crimes, crimes against humanity and ethnic cleansing of his supposed role in the war in Darfur.
