Eritrea's relations with its neighbors other than Djibouti also are somewhat strained. Although a territorial dispute with Yemen over the Haynish Islands was settled by international arbitration, tensions over traditional fishing rights with Yemen resurfaced in 2002. Relations with Sudan also were colored by occasional incidents involving the extremist group, Eritrean Islamic Jihad (EIJ)--which the Eritrean Government believes is supported by the National Islamic Front government in Khartoum--and by continued Eritrean support for the Sudanese opposition coalition, the National Democratic Alliance.
