Islamic State jihadist group claimed responsibility for the rocket attacks on the headquarters of Yemen's internationally recognized government in the southern Yemeni city of Aden.

The Sunni jihadist group, in an online statement, said that it had carried out four suicide attacks against the Saudi-backed establishments in the country, reported AFP. The Islamist terror outfit further said its fighters, Abu Saad Al Adani and Abu Mohammaed Al Sahli, carried out attacks on the government headquarters.

Khaled Bahah, the vice president and prime minister, and members of his cabinet escaped unhurt after two rockets struck Al Qasr Hotel & Resort, which is also serving as the Yemeni government's temporary headquarters, in the port city of Aden on Tuesday morning, as HNGN reported previously.

Fifteen coalition members and regime-loyal soldiers were killed and several others wounded in the attacks, reported Japan Times.

"Today's attack does not affect anybody. On the contrary, it binds us together more. We had come here to work and we know that there are security gaps . . . But this now prompts us to do more in the framework of reinforcing security in a bigger way by the general security services and armed forces," Bahah said after the attack, according to Reuters.

Yemen's internationally recognized government of President Abd-Rabbu Mansour Hadi returned from exile in Saudi Arabia and established temporary headquarters in the hotel last month. Hadi was forced to flee the country after Iran-backed Houthi rebels captured the capital Sanaa and vast areas of the war-torn country last year.
