AFP reports that a suicide car bomb exploded in Aden, Yemen on Monday, killing four loyalists.
The explosion wounded at least five others, though an official count has not been released.
A security official confirmed to AFP that an explosives-filled car slammed into a gathering of Pro-Hadi forces in Yemen's temporary capital of Aden.
Embattled President Abedrabbo Mansour Hadi relocated the government and loyalist forces to Aden over the summer, as Houthi forces still strongly control the previous capital, Sanaa.
No group has released a statement about the motives behind the attack. Daesh claimed responsibility for similar suicide bombings in Yemen earlier in 2016.
Yemen has been in the midst of a civil war between Pro-Hadi forces and Houthi rebels since March 2015, and both groups are backed by foreign funding. Al-Qaeda and Daesh also having a growing presence in the country, as the instability has allowed the militant groups to gain ground.
