The Arab League voiced on Tuesday concern over the recent developments in Yemen's southern port city of Aden.
"The recent developments will cause negative impacts on the Yemen's stability, territorial integrity and regional integration," a statement of the Arab League said.
"Dividing Yemen would lead to more chaos in the country," the pan-Arab organization warned.
It called for consensus among the conflicting parties to combat terrorism and achieve peace through dialogue and negotiation.
On August 10, the Emirati-backed separatist STC's forces seized full control over the Yemeni southern port city of Aden, seat of the official government, following violent clashes with official army that left 40 people killed and 260 others injured, according to UN release seizure of Aden.
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.
Saudi Arabia, along with UAE, has been leading a military coalition in Yemen since 26 March 2015, in support of forces loyal to President Abd Rabbu Mansour Hadi to retake northern areas controlled by Houthi group (Ansar Allah).
Southern separatists have exploited Yemen's war to enhance their presence, backed by the UAE that helped establishment of STC in May 2017 to consist of Yemeni southern 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.
