Witnesses told Xinhua that security forces loyal to the STC also surrounded and stormed the 4th Presidential Guard camp in the eastern part of Aden.
The officials said Hadi's prime minister and several Cabinet members would leave imminently to Riyadh.
A spokesman for the Saudi-led coalition that backs Hadi is calling for restraint by the separatists and for the government to listen to their "political and social" demands. The separatist forces did not enter the palace itself and were stopped by Saudi Arabian troops who have been guarding the palace for the past months.
The violence broke out after forces loyal to the Southern Transitional Council (STC) reportedly seized the government headquarters in Aden on Sunday.
Recently, southern separatists gave Hadi a week-long ultimatum to replace the government, which they accused of corruption and incompetence.

Saudi Arabia and UAE are the main partners in the Arab coalition that has been waging war on the Iran-backed Houthi rebels which took over the Yemeni capital Sanaa in September 2014.
"The coalition will take all the measures it deems necessary to restore stability and security in Aden", it said in a statement on Tuesday. He was believed to be in Saudi Arabia, where he has spent much of his time for the past three years.
According to Yemeni sources, Hadi urged all his forces "to confront any insurgency in Aden decisively and crush the separatist militias".
The coalition also imposed air and sea blockade to prevent weapons from reaching Houthis, who are in control of most of the northern Yemeni provinces, including the capital Sanna.
The clashes have sparked fears of a repeat of the 1986 South Yemen civil war, a failed socialist coup which killed thousands in just six days and helped pave the way for the 1991 unification of South and North Yemen.
Yemen was unified militarily in 1990 after a protracted war, but an active secessionist movement remained in and around Aden ever since, and they appear to have finally found an opening to reassert themselves.
