Rocket attacks hit the Al-Kasr Hotel in Yemen's southern port city of Aden where the transition government was staying, an official said on Tuesday.
Three rockets landed on the hotel early today but no one of the government members was injured, the official said, while accusing the Houthi militants of the attacks.
Other sources said rockets targeted other installations where troops from the Saudi-led coalition are staying killing and injuring around a dozen of them.
The sources did not reveal the nationalities of the troops that were guarding the government.
Vice President and premier Khalid Bahah and the caving returned to Aden last month after a six-month exile in Saudi Arabia.
Their return came after the Yemeni forces and the coalition retook Aden along with most of southern regions from the Houthi militants.
Since it came back, the government with direct help from Saudi Arabia and UAE has been busy with restoring security and rehabilitating public offices in Aden that had been destroyed during the conflict.
Today's attacks on the hotel coincided with persistent battles between the Yemeni forces backed by the coalition and the Houthi militants in some cities including Taiz and Marib.
Two days ago, the Houthi militants, who seized power in late 2014, vowed painful revenge for devastating blows their forces have lately received in Taiz and Marib.
The coalition has been bombing the militants since late March.
