Two senior Kenyan government officials have been charged in court with fraud over the building of a $3.2bn (£2.5bn) Chinese-funded railway line, BBC reports.
The two are accused of paying more than $2m in compensation to private firms which falsely claimed to own land through which the line ran.
The officials and 15 other accused have pleaded not guilty to the charges.
The railway line was Kenya’s biggest infrastructure project since independence from the UK in 1963.
President Uhuru Kenyatta opened it last year, hailing it as a new chapter in the East African state’s history.
The line runs between the port city of Mombasa and the capital, Nairobi, and construction was completed 18 months early.
It is supposed to eventually connect landlocked South Sudan, eastern Democratic Republic of Congo, Rwanda, Burundi and Ethiopia to the Indian Ocean.
But the project has been marred by corruption allegations, and claims by economists that the cost was too high.
Kenya Railways head Atanas Maina and National Land Commission chairman Muhammad Swazuri were charged with fraud on Monday, following their arrest on Saturday.
Many Kenyans have welcomed the detention of the two men who were seen as “untouchables” because of the political influence they wielded.
They were handcuffed after they took their seats in the dock at a magistrate court in Nairobi.
