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.
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 in May 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.
It ran up a loss of about $100m in its first year of operation, official figures show.
