Attacks in Aden on a hotel used by Yemen’s prime minister and two military installations have killed 15 Saudi-led coalition troops and pro-government fighters, Emirati state media say.
Explosions rocked the Qasr hotel, the headquarters of the UAE’s forces in the city and a camp early on Tuesday.
Prime Minister Khaled Bahah and members of his government escaped unharmed.
The UAE blamed rocket-fire from Houthi rebels, but Islamic State (IS) said suicide bombers were responsible.
Jihadist militants from IS and al-Qaeda have reportedly been seen on the streets of Aden since southern militiamen, backed by coalition forces, drove the Houthis out of the city in July before advancing northwards and creating a security vacuum.
Yemeni government spokesman Rajeh Badi told the Associated Press that the Qasr hotel in the al-Buraiqa district, the UAE’s military headquarters in the nearby palace of Sheikh Farid al-Awlaqi, and a camp where Emirati troops are housed in the al-Shaab district were all hit by rockets fired from outside the city limits.
The prime minister and his ministers were safe and unhurt, he said, adding that the cabinet would hold an emergency meeting about the attack.
The official Saudi Press Agency also cited a coalition statement blaming rocket fire. Coalition forces had “responded to the source of fire and destroyed the vehicles” used to launch them, it said.
But a statement posted online by a newly formed IS affiliate, Aden-Abyan Province, asserted that it had carried out four suicide attacks, two of them targeting the Qasr hotel.
The local newspaper Aden al-Ghad had earlier cited Yemeni security sources as saying the explosions were the result of car bombings.
The sources said gunmen armed with automatic weapons and mortars had fought guards stationed at the main gate of the Qasr Hotel, before driving an explosives-packed vehicle into the compound and blowing it up.
The attacks on the other two locations also saw gunmen attack before detonating car bombs, the sources added.
Aden al-Ghad also quoted Yemen’s Minister of Youth and Sport, Nayef al-Bakri, as saying the attacks involved suicide bombers.
Local politician Mohammed al-Saadi told the Reuters news agency that Mr Bahah and several ministers were sleeping at the Qasr hotel when it was attacked. “They and all the government workers have now been moved to a secret place,” he said.
Before IS claimed responsibility, the UAE’s minister of state for foreign affairs had blamed the attacks on the Houthis and allied army units loyal to former President Ali Abdullah Saleh, who he claimed were determined to destroy Yemen.
