Nobel Peace Prize winner Muhammad Yunus was sworn in to head Bangladesh's interim government.
It came days after a student-led uprising ended Prime Minister Sheikh Hasina's 15-year rule, AFP reported.
"I will uphold, support and defend the constitution," Yunus said during the swearing-in ceremony, adding that he would carry out his duties "sincerely."
Yunus was sworn in at the presidential palace in the capital Dhaka in the presence of political leaders, civil society leaders, generals and diplomats.
More than a dozen members of his cabinet, who are titled as advisers rather than ministers, were also sworn in.
Among them were senior leaders of the group Students Against Discrimination, which led the weeks-long protests.
Others included Tuheed Hossain, former foreign minister, and Hassan Arif, former attorney general.
Syeda Rizwana Hasan, a multi-award winning environmental lawyer, and Asif Nazrul, a law professor and writer, also took the oath.
Among those sworn in was Adilur Rahman Khan, a prominent human rights activist who was sentenced to 2 years in prison by Hasina's government. | BGNES
