Bashir, who had seized power in an Islamist-backed coup in 1989, was deposed following months of nationwide protests against his ironfisted rule. Dressed in a white traditional Sudanese tobe and wearing spectacles, Abdalla took the oath as foreign affairs minister at the presidential palace along with 17 other ministers.
The swearing-in ceremony was held in the presence of members of the joint civilian-military ruling sovereign council, including its chief General Abdel Fattah al-Burhan. The sovereign council will oversee a 39-month transition period as Sudan embarks on the road to civilian rule, the main demand of protesters.
Abdalla, whose studies were partly in the United States, was one of the first three women to join Sudan's foreign ministry as a diplomat after graduating from Khartoum University in 1971 with a degree in economics and political science. But she was sacked in 1991 by the then administration of Bashir, who had seized power two years before in a coup.
Abdalla's appointment is part of new Prime Minister Abdalla Hamdok's plan to have a government made up of technocrats and one that reflects gender balance.
