The head of Yemen's separatist movement said he was ready to take part in Saudi-brokered peace talks after clashes with pro-government forces killed dozens in second city Aden.
Abu Dhabi's powerful crown prince, who met Saudi Arabia's King Salman on Monday, also backed Riyadh's call for dialogue.
The fighting in Yemen's southern port city pitted Saudi-backed government forces against the UAE-trained Security Belt Force, both of which have been fighting Huthi rebels who seized the capital Sanaa in 2014.
