Yemen has been at war since Iran-backed Houthi rebels ousted the government in 2014, triggering a Saudi-led military intervention, but a new internal conflict has been brewing in recent weeks.

The face-off involves rival armed factions loosely grouped under the government but separately backed by the United Arab Emirates and Saudi Arabia.

The UAE on Tuesday said it was pulling its remaining forces out of Yemen, following a Saudi demand to withdraw within 24 hours as tensions escalate over a sweeping offensive by Abu Dhabi-backed separatists, who have refused to pull back.
