The Nile is a major north-flowing river in northeastern Africa. The longest river in Africa, it has historically been considered the longest river in the world, though this has been contested by research suggesting that the Amazon River is slightly longer. The Nile is about 6,650 km long and its drainage basin covers eleven countries: Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan, and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan. AND THE Indus River is one of the main rivers of the Indo-Gangetic Plain in the Indian subcontinent. It flows through China, Jammu and Kashmir, and Pakistan. Originating in the Tibetan Plateau in the vicinity of Lake Manasarovar, the river runs a course through the Ladakh region of Jammu and Kashmir towards Gilgit-Baltistan, and then flows in a southerly direction along the entire length of Pakistan to merge into the Arabian Sea near the port city of Karachi in Sindh. The Indus is the longest river of Pakistan.
