A military source said to Al-Jazeera that the Sudanese army has gained control - today, Monday - over Mount Umm al-Tayyar, which is located in the depth of Sudan, about 7 kilometers from the border with Ethiopia, and that it is now moving to liberate all the lands occupied by Ethiopian militias.
The source, who is participating in the hostilities, added that the Ethiopian civilian population had evacuated most of the villages, but the Ethiopian military militias were resisting the advance of the Sudanese forces until Monday evening.
Earlier, the Commander-in-Chief of the Sudanese Army and Chairman of the Sovereignty Council, Abdel Fattah Al-Burhan, returned to Khartoum after he stayed in the army command in the Eastern Region for 3 days, accompanied by the Chief of Staff and other senior military leaders.
Al-Burhan assumed command of the eastern region for two days, overseeing the advance of the Sudanese forces, which were reinforced with ground and air supplies to confront the "Ethiopian attacks."
Gedaref State
In a related context, security sources in the Sudanese state of Gedaref told Al-Jazeera that the Sudanese armed forces had taken back 3 towns from the Ethiopian militia on the border between the two countries.
The Sudanese armed forces have pushed large military reinforcements in recent days, towards the sites of fighting with the Ethiopian militia in the Quraysh area in the Sudanese small Fashaqa sector.
The Sudanese government says that large border areas - the most prominent of which are the Greater Fasha and Lesser Fasha sectors - have been occupied by Ethiopian militias for more than 25 years.
The announcement of the restoration of those three towns comes amid a military build-up and tension on the borders, which led to the killing of Sudanese soldiers.
Ahead of an expected meeting tomorrow, Tuesday, of the joint commission on the borders between Sudan and Ethiopia, according to a statement issued by the office of Sudanese Prime Minister Abdullah Hamdok.
The border demarcation agreement dates back to May 1902 between Britain and Ethiopia, but there are still gaps in some points, which regularly cause accidents with Ethiopian farmers who come to work on lands that Sudan asserts that they fall within its borders.
