Libyan embassy in Sana’a lifted the new Libyan flag instead of the green flag, which represented the regime of leader Muammar Gaddafi on Thursday night.
Yemen has not yet announce its acceptance to the Transitional Council as the sole representative of the Libyan people instead of the Gaddafi regime, which collapsed after an armed popular revolution.
Analysts say that raising the new flag of the Transitional Council holds an indirect acceptance of the authorities in Sana'a to the changes in Libya.
Earlier this week, the Yemen delegation withdrew before the Arab League foreign ministers meeting to avoid recognition of the Interim Council of Libya.
Today marks the 42nd anniversary of September Revolution, which Gaddafi took over rule of Libya.
It was announced earlier this week the rebels in Libya are not in control over several key areas, including the city of Al Jawad, which lies about 126 km from the city of Sirte, Gaddafi's hometown.
