The 25th anniversary of the Good Friday Agreement has been marked by violence in Northern Ireland. The violence has been sparked by the refusal of the DUP to form a government.
The DUP is the only party that has refused to sign the agreement. Northern Ireland has been without a government for the last nine years due to a lack of understanding between unionists and republicans. The Irish government has said it is committed to working with the DUP on a new power-sharing agreement. It has also said it will not accept any changes to the Belfast Agreement, which was signed in 1998.
