Yemen’s Interior Minister Ahmed El-Meseery has said a leader of the southern separatist moment is “fomenting sedition” by calling on followers to topple the country’s internationally recognized government.

The minister said in a statement late Wednesday that the call by Hani Ben Braik, deputy head of the so-called Southern Transitional Council, only serves rebel Houthis.

An online video showed Ben Braik calling on Yemenis to march on the presidential palace in the southern city of Aden and topple Hadi’s government, AP said.

Yemen’s government forces have been at war with the Houthis, who control the north, since 2015. The conflict started in 2014 when the rebels captured the capital, Sanaa, and expelled President Abed Rabbo Mansour Hadi’s government. It is now based in the south, which is also the base of separatists.
