Amnesty International and the Nigerian Legal Defence and Assistance Project (LEPAD) on Monday expressed deep concern about human rights violations and an increase in political violence in the run-up to Nigeria's federal and state elections, scheduled for April and May 2003. In a joint statement, the organisations said that reports of political violence, including the assassination of political leaders, clashes between supporters of different political persuasions - both within political parties and between rival parties - and the intimidation and harassment of candidates and sympathisers had risen considerably in recent months.
