full_context: Document 1: Lake Vanda: Lake Vanda is a lake in Wright Valley, Victoria Land, Ross Dependency, Antarctica. The lake is 5 km long and has a maximum depth of 69 m. On its shore, New Zealand maintained Vanda Station from 1968 to 1995. Lake Vanda is a hypersaline lake with a salinity more than ten times that of seawater, more than the salinity of the Dead Sea, and perhaps even more than of Lake Assal (Djibouti), which is the world's most saline lake outside of Antarctica. Lake Vanda is also meromictic, which means that the deeper waters of the lake don't mix with the shallower waters. There are three distinct layers of water ranging in temperature from on the bottom to the middle layer of and the upper layer ranges from . It is only one of the many saline lakes in the ice-free valleys of the Transantarctic Mountains. The longest river of Antarctica, Onyx River, flows West, inland, into Lake Vanda. There is a meteorological station at the mouth of the river.
Document 2: Eritrea: The creation of modern-day Eritrea is a result of the incorporation of independent, distinct kingdoms and sultanates (for example, Medri Bahri and the Sultanate of Aussa) eventually resulting in the formation of Italian Eritrea. In 1947 Eritrea became part of a federation with Ethiopia, the Federation of Ethiopia and Eritrea. Subsequent annexation into Ethiopia led to the Eritrean War of Independence, ending with Eritrean independence following a referendum in April 1993. Hostilities between Eritrea and Ethiopia persisted, leading to the Eritrean–Ethiopian War of 1998–2000 and further skirmishes with both Djibouti and Ethiopia.
Document 3: History of Somaliland: The history of Somaliland, a region in the eastern horn of Africa bordered by the Indian Ocean, Gulf of Aden, and the east African land mass, begins with human habitation tens of thousands of years ago. It includes the civilizations of Punt, the Ottomans, and colonial influences from Europe and the Middle East.
Document 4: Eritrea: The Scottish traveler James Bruce reported in 1770 that Medri Bahri was a distinct political entity from Abyssinia, noting that the two territories were frequently in conflict. The Bahre-Nagassi ("Kings of the Sea") alternately fought with or against the Abyssinians and the neighbouring Muslim Adal Sultanate depending on the geopolitical circumstances. Medri Bahri was thus part of the Christian resistance against Imam Ahmad ibn Ibrahim al-Ghazi of Adal's forces, but later joined the Adalite states and the Ottoman Empire front against Abyssinia in 1572. That 16th century also marked the arrival of the Ottomans, who began making inroads in the Red Sea area.
Document 5: Somalia: Somalia (/ səˈmɑːliə / so - MAH - lee - ə; Somali: Soomaaliya; Arabic: الصومال ‎, translit. aṣ - Ṣūmāl), officially the Federal Republic of Somalia (Somali: Jamhuuriyadda Federaalka Soomaaliya; Arabic: جمهورية الصومال الفيدرالية ‎, translit. Jumhūrīyat aṣ - Ṣūmāl al - Fidirālīyah), is a sovereign state with its territory located in the Horn of Africa. It is bordered by Ethiopia to the west, Djibouti to the northwest, the Gulf of Aden to the north, the Guardafui Channel and Indian Ocean to the east, and Kenya to the southwest. It is separated from Socotra by the Guardafui Channel in the northeast. Somalia has the longest coastline on Africa's mainland, and its terrain consists mainly of plateaus, plains and highlands. Climatically, hot conditions prevail year - round, with periodic monsoon winds and irregular rainfall.
Document 6: Eritrea: Eritrea (/ˌɛrᵻˈtreɪ.ə/ or /ˌɛrᵻˈtriːə/;, officially the State of Eritrea, is a country in East Africa. With its capital at Asmara, it is bordered by Sudan in the west, Ethiopia in the south, and Djibouti in the southeast. The northeastern and eastern parts of Eritrea have an extensive coastline along the Red Sea. The nation has a total area of approximately 117,600 km2 (45,406 sq mi), and includes the Dahlak Archipelago and several of the Hanish Islands. Its name Eritrea is based on the Greek name for the Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa), which was first adopted for Italian Eritrea in 1890.
Document 7: Eritrea: During the Middle Ages, the Eritrea region was known as Medri Bahri ("sea-land"). The name Eritrea is derived from the ancient Greek name for Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa, based on the adjective ἐρυθρός erythros "red"). It was first formally adopted in 1890, with the formation of Italian Eritrea (Colonia Eritrea). The territory became the Eritrea Governorate within Italian East Africa in 1936. Eritrea was annexed by Ethiopia in 1953 (nominally within a federation until 1962) and an Eritrean Liberation Front formed in 1960. Eritrea gained independence following the 1993 referendum, and the name of the new state was defined as State of Eritrea in the 1997 constitution.[citation needed]

Document 9: Somalis: The revolutionary army established large-scale public works programs and successfully implemented an urban and rural literacy campaign, which helped dramatically increase the literacy rate. In addition to a nationalization program of industry and land, the new regime's foreign policy placed an emphasis on Somalia's traditional and religious links with the Arab world, eventually joining the Arab League (AL) in 1974. That same year, Barre also served as chairman of the Organization of African Unity (OAU), the predecessor of the African Union (AU).
Document 10: Eritrea: In 1922, Benito Mussolini's rise to power in Italy brought profound changes to the colonial government in Italian Eritrea. After il Duce declared the birth of the Italian Empire in May 1936, Italian Eritrea (enlarged with northern Ethiopia's regions) and Italian Somaliland were merged with the just conquered Ethiopia in the new Italian East Africa (Africa Orientale Italiana) administrative territory. This Fascist period was characterized by imperial expansion in the name of a "new Roman Empire". Eritrea was chosen by the Italian government to be the industrial center of Italian East Africa.
Document 11: Somalis: Somalis constitute the largest ethnic group in Somalia, at approximately 85% of the nation's inhabitants. They are traditionally nomads, but since the late 20th century, many have moved to urban areas. While most Somalis can be found in Somalia proper, large numbers also live in Ethiopia, Djibouti, Kenya, Yemen, the Middle East, South Asia and Europe due to their seafaring tradition.
Document 12: Lake Assal (Djibouti): Lake Assal ( , literally 'honey lake') is a crater lake in central-western Djibouti. It is located at the western end of Gulf of Tadjoura in the Tadjoura Region, touching Dikhil Region, at the top of the Great Rift Valley, some west of Djibouti city. Lake Assal is a saline lake which lies below sea level in the Afar Triangle, making it the lowest point on land in Africa and the third-lowest point on Earth after the Sea of Galilee and the Dead Sea. No outflow occurs from the lake, and due to high evaporation, the salinity level of its waters is 10 times that of the sea, making it the third most saline body of water in the world behind Don Juan Pond and Gaet'ale Pond. Lake Assal is the world's largest salt reserve, which is exploited under four concessions awarded in 2002 at the southeast end of the lake; the major share of production (nearly 80%) is held by Société d’Exploitation du Lac and Société d’Exploitation du Salt Investment S.A de Djibouti. It is situated approximately west of the nation's capital Djibouti City.
Document 13: Israel: The Jordan River runs along the Jordan Rift Valley, from Mount Hermon through the Hulah Valley and the Sea of Galilee to the Dead Sea, the lowest point on the surface of the Earth. Further south is the Arabah, ending with the Gulf of Eilat, part of the Red Sea. Unique to Israel and the Sinai Peninsula are makhteshim, or erosion cirques. The largest makhtesh in the world is Ramon Crater in the Negev, which measures 40 by 8 kilometers (25 by 5 mi). A report on the environmental status of the Mediterranean basin states that Israel has the largest number of plant species per square meter of all the countries in the basin.

Document 15: Somalis: Somali people in the Horn of Africa are divided among different countries (Somalia, Djibouti, Ethiopia, and northeastern Kenya) that were artificially and some might say arbitrarily partitioned by the former imperial powers. Pan-Somalism is an ideology that advocates the unification of all ethnic Somalis once part of Somali empires such as the Ajuran Empire, the Adal Sultanate, the Gobroon Dynasty and the Dervish State under one flag and one nation. The Siad Barre regime actively promoted Pan-Somalism, which eventually led to the Ogaden War between Somalia on one side, and Ethiopia, Cuba and the Soviet Union on the other.
