They added that the retreating UAE forces transported tanks, armored vehicles and heavy weapons aboard five tankers towards their headquarters in Boraiqa district."

The Yemeni legitimate government dismissed the STC seizure as another coup in Aden, following the Houthi coup in Sana'a, holding the UAE and STC responsible for ramifications.
On the same day, the Saudi-led coalition called on the STC to pull back its forces from positions its forces seized last Saturday, and threatened to "use military force."
Riyadh called for immediate dialogue in the kingdom between Yemeni government and the STC.
While they quit some government civil offices, STC troops rejected withdrawal from military camps and security sites.
Southern separatists have exploited Yemen's war to enhance their presence in the south, backed by the UAE that helped the STC establishment in May 2017 to consist of bodies calling for separation, but also trained and armed local forces under STC command.
The STC claims to be representative for Yemeni southerners and seeks to impose control over all the south, but it is not fully supported by people there.
