North and South Yemen came together in 1990 to form a united country after years of conflict.

However, it's been an uneasy union, and the civil war that began in 2015 is deepening the divide.

Separatists from the Southern Transitional Council (STC) are part of a Saudi-UAE military coalition fighting the Houthi rebels.

But in a dramatic twist last week, the UAE-backed separatists took over the city of Aden, the seat of the Saudi-backed Yemeni government.

Thousands of people waved the old South Yemen flag during a rally to support the STC.

How will the developments affect the civil war and the fragile Saudi-UAE coalition?
