Nigeria has filed charges against former US Vice-President Dick Cheney over a scandal involving a former subsidiary of Halliburton energy firm.
The case, brought by the country’s anti-corruption agency, centres on engineering firm KBR, which admitted bribing officials.
Mr Cheney’s lawyer has called the allegations “entirely baseless”.
Mr Cheney was Halliburton’s chief executive before becoming vice-president to George W Bush in 2001.
The Economic and Financial Crimes Commission (EFCC) said it had filed 16 charges against Mr Cheney, Halliburton Chief Executive David Lesar, and two other executives.
It also filed charges against Halliburton as a company and four associated businesses.
