Aden: At least one person was killed in renewed fighting in Aden, the seat of Yemen’s Saudi-backed government, a day after clashes between supporters of rival political groups killed around three, local sources said.

Sounds of gunfire echoed through the southern port city while smoke and fire could be seen rising from the Jebel Hadid area, part of the Crater district which houses the hilltop presidential palace, a Reuters witness and residents said.

Clashes erupted on Wednesday between presidential guard forces and supporters of the southern separatist movement, after the funeral of those killed in a Houthi attack last week on a military parade which has increased frictions between Aden’s parties.

On Thursday a Reuters witness said gunfire was exchanged between presidential guard forces and a southern separatist camp.

The separatists and the internationally recognised government of President Abd-Rabbu Mansour Hadi are nominally united in their battle against the Houthis, but they have rival agendas for Yemen’s future.

The southern separatists have accused a political party allied to Hadi of being involved in the parade attack.
