Former Sudanese president Omar al-Bashir was denied bail by a court in Khartoum in a corruption trial that began earlier this year, according to officials on Saturday.

Al-Bashir, who ruled Sudan for nearly 30 years, is charged with illicit financial gains, bribery and accepting gifts in an unofficial manner, including 90 million U.S. dollars in cash from Saudi royals.

Last week, the 75-year-old said he received 25 million U.S. dollars from Saudi Crown Prince Mohammed bin Salman, but claimed he did not use the money for his own benefit.

More than 130 million U.S. dollars were found when the former president's house was raided after he was removed from power in April, according to investigators.

The charges carry maximum prison sentences of about 10 years. The next hearing is set for September 14.

On Saturday, al-Bashir's office manager testified in the former president's fourth court hearing that the ex-president was the only one with a key to a room at the presidential palace holding millions of euros.

Speaking as a defense witness, Yasser Basheer said the ousted leader gave him more than 11 million U.S. dollars in cash in his final months of rule for delivery to different parties.

While al-Bashir did not speak at Saturday's hearing, he denied the charges when he spoke last week.

Nearly 130 lawyers from al-Bashir's team reportedly argued that the money was given to the former president as a person and not as president.
