The arrest warrant against the Sudanese President Omar Al-Bashir seems to be imminent. The New York Times is reporting that the arrest warrant has been approved - but it seems the ICC is keeping it underraps as per this SudanTribune article. This could be a ploy by the ICC to keep the arrest warrant a secret, allowing them to arrest the President if he decides to go abroad and visit one of the member states of the Rome Statute, the agreement that created the court, without having publicly announced the arrest warrant. Or, they can simply still be in the process of working out the final details. Only time will tell. All the while, 'negotiations' between the Justice and Equality Movement (JEM) and the government are taking place in Doha, Qatar.
No one knows what (if any) tangible effects this arrest warrant will have on the peace talks and the situation in Sudan as a whole. Some, like Alex de Waal believe this could lead to a very dangerous situation.
