The Houthi movement, which controls the capital, Sanaa, has claimed responsibility for Thursday's attack in the southern city of Aden which targeted a military parade at a camp belonging to the Yemeni Security Belt forces. The forces are backed by the United Arab Emirates, a key partner in a military alliance assembled by Saudi Arabia to fight the rebels.
In a separate attack in Aden, a suicide bomber also hit a police station.
Al Jazeera's Mohammed Alattab in Sanaa, and Mahjoob Zweiri, the director of Qatar University's Gulf Studies Center in Doha, discuss these latest developments.
