ISIS in Yemen claimed responsibility for coordinated suicide attacks which targeted the Yemeni government and the Arab military coalition supporting it in the southern city of Aden on Tuesday.
Two separate bombings by ISIS were the first known attacks by the militant group on the Yemeni administration and killed 15 Arab and Yemeni troops.
The Yemeni administration turned the al-Qasr hotel in the northwest of the port city into its headquarters after returning to the country last month.
According to an announcement on the UAE's official news agency's twitter account, four Emirati soldiers and 11 other troops from the Saudi-led coalition were killed in the compound.
Yemeni officials were unhurt in the attack on Al Qasr Hotel. President Abd-Rabbu Mansour Hadi is believed to be abroad while Prime Minister and Vice President Khaled Bahah and his ministers also escaped unharmed.
Al Qasr Hotel has been used by Hadi’s government as informal headquarters since its gradual return from exile in Riyadh two months ago. The hotel is guarded by troops from the United Arab Emirates.
UAE Minister of State for Foreign Affairs Anwar Gargash tweeted about the incident shortly after it ocurred, blaming the Iranian backed Houthi rebels and militias loyal to deposed president Ali Abdullah Salih for the attack.
استهداف فندق القصر، مقر الحكومة اليمنية، محاولة يائسة اخرى في جهل وتجاهل واضح لما يحصل على الارض، ولعل نهوض عدن أغاض قوى الفساد والظلام.

Gargash said the attack was proof that “the Houthis and Saleh were determined to destroy Yemen”.
"The situation on the ground shows that they are waging a losing battle and that their role has been diminished to retreating on the ground and to try to inflict damage with mines, ambushes and rockets," Gargash tweeted in another message.
War-torn Yemen has been suffering from clashes since the beginning of Saudi-led coalition operations last March, when the Houthis seized the country's capital Sanaa and advanced towards Aden last September, forcing Hadi and his government to flee to Saudi Arabia and ask the Kingdom to intervene to help “Save Yemen.”
The war in Yemen has triggered an unprecedented humanitarian crisis in the country. The UN declared the situation in Yemen to be a level-three humanitarian emergency, the highest on its scale, after about 80 percent of the country’s population fell into dire need of humanitarian aid.
Twenty million people in the country are in need of aid, 13 million are facing food shortages and 9.4 million are having difficulties accessing drinking water.
The United Nations reported that nearly 4,900 people - including more than 2,100 civilians - have been killed in fighting and air strikes since March 26.
