The World Anti-Doping Agency (WADA) says on Thursday that Nigeria’s national anti-doping agency had been declared non-compliant.

Jonathan Taylor, the chair of WADA’s independent compliance review committee, informed its board at a meeting in Baku that the Nigerian agency did not meet international anti-doping standards, WADA wrote on Twitter.

Last year the Nigerian National Anti-Doping Committee collected 28 samples, seven of which tested positive, according to data from WADA.
