Southern separatists backed by the UAE have seized control of a key military base in the coastal city of Aden after a UAE fighter jet bombed the facility, according to a senior Yemeni official.

The official told Al Jazeera that the fighters are from the Southern Resistance Forces (SRF) - the armed wing of the Southern Transitional Council (STC), a political movement demanding secession for southern Yemen.

The fighters seized the base early on Tuesday, despite a ceasefire being brokered by coalition partners Saudi Arabia and the UAE hours earlier.
