Rising tension in Horn of Africa region

In the initial weeks of 2018, the Sudanese president Omar al-Bashir announced the closure of the border with Eritrea which was was followed by the deployment of militia forces to the bordering regions. The reason for the border closing has not officially been made clear and Sudan has denied tension between the two countries. This manoeuvre comes just after the declaration of a six-month state of emergency in the Sudanese regions of Kassala and North Kordofan. The official motivation given for the state of emergency  was the Sudanese campaign against the trafficking of human beings, weapons, and drugs and in those border regions.
