Nigeria: Anti-corruption agency launches $4m fraud probe

Nigeria's anti-corruption agency has launched a probe into allegations of fraud after a massive overpayment was made to a maritime organisation. More than $4m (£2.2m) was paid to the International Seabed Authority (ISA) in March for a bill of $22,000 (£12,000), according to the president's office. Officials say an investigation has been launched into foreign ministry staff.
