Eritrea sustains that the border has been occupied by Ethiopian forces. ONU has sent a mission to delimiting and to demarcating once for all the border and that deny a new war between two sides. Ethiopia, angry about this “insult”, has denied to ONU from February 2008 to send own forces as force of peace. Now, that the ONU mission will be broken and there won’t be more any that will control the border, a new war will be at horizon. The last war between Ethiopia and Eritrea lasted 2 years, has caused thousands of dead.
