Separatists in southern Yemen have declared self-rule, breaking a peace deal signed in November with the internationally recognized government.

The Aden-based Southern Transitional Council, which is supported by the United Arab Emirates, declared a state of emergency, saying it would govern the port city and other southern provinces.

The Saudi-backed Yemeni government warned of “dangerous and catastrophic consequences”.

“The announcement by the so-called transitional council of its intention to establish a southern administration is a resumption of its armed insurgency... and an announcement of its rejection and complete withdrawal from the Riyadh agreement”, - said Yemen’s Foreign Minister Mohammed Al-Hadhrami.
