Five militants of the Southern Transitional Council were killed by snipers, while four soldiers died in clashes.
The day before clashed resulted in 12 people dead and over 130 wounded, while supporters of a movement to restore South Yemen's independence from the North reportedly captured several government facilities.
Clashes between former allies — the Saudi-led pro-government forces and militants of the Southern Transitional Council erupted the day after the internationally recognized government hadn't met a deadline for the resignation.
Southern rebels initially backed internationally-recognized Yemen President Abdrabbuh Mansour Hadi, who fled from advancing Houthi rebels to his hometown of Aden, and alongside the Saudi-led coalition helped push the Houthis away from southern regions.
Hadi, in turn, rejected the ultimatum and banned public gatherings before January 28 — subsequently, clashes erupted. The president has called on the Saudi-led coalition to help and currently facing two fronts — one against the Houthis and a second against the Southern rebels.
