evidence: Djibouti accused Eritrea of deploying troops to occupy the contested area, known as Ras Doumeira, after a contingent of 450 Qatari peacekeepers departed last week. If true, the move could threaten a return to war for the first time since the countries fought over the land in 2008. [...] Ras Doumeira has been a source of tension since 1996, when a Djiboutian official accused Eritrea of shelling the area. Tensions continued in 1999 when Eritrea accused Djibouti of supporting Ethiopia.
