Human Rights Watch writes to urge President Köhler to use his forthcoming visit to Nigeria to raise specific human rights concerns with President Umaru Yar'Adua and his administration. Serious problems include rampant government corruption and mismanagement that undermine the realization of the right to basic healthcare and education; political and intercommunal violence fomented by government officials and politicians; and widespread use of extrajudicial executions, torture, and extortion by state security forces.
