Yemen's southern separatists on Tuesday accused an Islamist party of complicity in last week's deadly attack on Aden, the seat of government, exposing rifts in the Saudi-backed coalition battling the Iran-aligned Houthi movement.
The separatists and Islamist party are united in their wider war on the Houthis, but have rival agendas for
Yemen, and frictions between them over Thursday's attack could destabilize the southern port city that is the coalition's sole stronghold.
