Question: Which portion of the Nile runs from the country where most Israeli blacks have emigrated from and the country where Khartoum is located?

The Nile (Arabic: النيل‎, written as al-Nīl; pronounced as an-Nīl) is a major north-flowing river in northeastern Africa, and is the longest river in Africa and the disputed longest river in the world (Brazilian government claims that the Amazon River is longer than the Nile). The Nile, which is about 6,650 km (4,130 mi) long, is an "international" river as its drainage basin covers eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan and Egypt. The White Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. It flows north through Tanzania, Lake Victoria, Uganda and South Sudan. In particular, the Nile is the primary water source of Egypt and Sudan.The river Nile has two major tributaries, the White Nile and Blue Nile. The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet just north of the Sudanese capital of Khartoum.The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta and flows into the Mediterranean Sea. Egyptian civilization and Sudanese kingdoms have depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, and nearly all the cultural and historical sites of Ancient Egypt are found along river banks. <SEP> About 150,000 East African and black people live in Israel, amounting to just over 2% of the nation's population. The vast majority of these, some 120,000, are Beta Israel, most of whom are recent immigrants who came during the 1980s and 1990s from Ethiopia. In addition, Israel is home to over 5,000 members of the African Hebrew Israelites of Jerusalem movement that are descendants of African Americans who emigrated to Israel in the 20th century, and who reside mainly in a distinct neighborhood in the Negev town of Dimona. Unknown numbers of black converts to Judaism reside in Israel, most of them converts from the United Kingdom, Canada, and the United States. <SEP> the tekezé river rises in the central ethiopian highlands near mount qachen within lasta, from where it flows west, north, then west again, forming the westernmost border of ethiopia and eritrea from the confluence of the tomsa with the tekezé at to the tripoint between the two countries and sudan at . after entering northeastern sudan at the tripoint it joins the atbarah river, which is a tributary of the nile. the tekezé is perhaps the true upper course of the atbarah, as the former follows the longer course prior to the confluence of the two rivers. <SEP> Although it is the smallest state by area (22,142 km), it is the most populous (5,274,321 in 2008 census). Khartoum State () is one of the eighteen states of Sudan. It contains the country's second largest city by population, Omdurman, and the city of Khartoum, which is the capital of the state as well as the national capital of Sudan. The capital city contains offices of the state, governmental and non-governmental organizations, cultural institutions, and the main airport. <SEP> uganda (/ juː ˈɡændə / yew - gan - də or / juː ˈɡɑːndə / yew - gahn - də), officially the republic of uganda, is a landlocked country in east africa. it is bordered to the east by kenya, to the north by south sudan, to the west by the democratic republic of the congo, to the south - west by rwanda, and to the south by tanzania. the southern part of the country includes a substantial portion of lake victoria, shared with kenya and tanzania. uganda is in the african great lakes region. uganda also lies within the nile basin, and has a varied but generally a modified equatorial climate.
