"Bin Mubarak has left the location where he had been kept, he is ok. Bin Mubarak was handed over to the delegation of elders in the [southern] Shabwa province," the source said Tuesday, adding that the delegation included a member of the Yemeni parliament.
Yemeni President Abd Rabbuh Mansur Hadi submitted his resignation last week. The country's cabinet also offered its resignation, following clashes with Shia Houthi rebels.
The Houthis are the main opposition force in Yemen. They have been carrying out protests in the country since mid-August, demanding the resignation of the Yemeni government. Houthi militias have taken over many Yemeni cities, including parts of Sanaa. The fighters claim their actions are aimed at protecting civilians from terrorism and discrimination by the government.
