A hotel in Yemen’s second city of Aden which Khaled Bahah, the prime minister and vice president, and members of the government are using as a base has been hit by several blasts.
Government officials said Bahah was not hurt in Tuesday morning’s attack, but there were other casualties.
It was not clear whether the casualties included members of government.
Residents told the Reuters news agency that unidentified assailants had fired missiles at al-Qasr Hotel.
One missile appeared to have been fired at the hotel’s gate, they said.
A second missile landed nearby, while a third landed in Aden’s Buraiqah district, residents said.
Some reports spoke of rocket-propelled grenades being used.
AFP news agency reported smoke rising from the hotel, which is located in Aden’s western suburbs.
Ambulances and civil defence forces were on the scene, witnesses said, adding that the rockets hit the entrance of al-Qasr Hotel.
Bahah and his ministers were installed in Aden – declared Yemen’s provisional capital after it was taken back from Iran-allied Shia Houthi fighters in mid-July – after they spent six months in exile in Saudi Arabia.
Al-Qasr Hotel has been the headquarters of President Abd-Rabbu Mansour Hadi’s government since his return to Yemen.
The hotel has been guarded by troops from the United Arab Emirates, one of the key members of the Arab coalition that has been fighting since March to end Houthi control of Yemen and restore Hadi to power in the capital, Sanaa. Al Jazeera
