UAE warplanes attack Saudi-backed government in Aden
The UAE, which has backed southern separatists in Yemen, has been attacking forces loyal to the internationally-recognised government.
Local sources say that up to 40 people were killed in the Emirati strikes.
Mohamed al-Oban, a commander of the special forces in the Abyan province, said the troops were headed towards Aden on Thursday when the airstrikes took place.
Al-Oban didn't specify who was behind the strikes, only saying that the planes were from the Saudi-led coalition. The UAE is a key member of the Saudi-led military coalition in Yemen.The reports came in hours after Yemen separatists announced they had regained full control of Aden, just a day after the government took over the strategic city following a battle between the warring factions.
The separatists, who seek an independent South Yemen, seized Aden on August 10 following heavy clashes with government troops. The major gain saw them press on to take other strategic areas, before being pushed back.
Saudi Arabia seeks to preserve Yemen's unity and is a staunch supporter of the Hadi government, whereas the UAE is backing the separatists who seek an independent South Yemen.
Saudi Arabia has in recent weeks been privately expressing "extreme irritation" with close ally UAE when talking to Yemeni government officials.
