A hotel in Aden housing Yemen ' s prime minister and his cabinet has been hit by a rocket attack on Tuesday. There are reports of casualties, though not among ministers staying there, BBC reported. The Qasr hotel has been used a seat of government since a Saudi-led coalition forced Houthi rebels from Aden, Yemen's second city. The Houthi rebels advanced on the city and in March forced President Abdrabbuh Mansour Hadi and the government to flee to Saudi Arabia. In July, pro-government militiamen and soldiers drove the Houthis and allied army units loyal to former President Ali Abdullah Saleh out of the port city with the help of coalition ground forces. Residents have complained that the city has descended into chaos and lawlessness, with jihadist militants affiliated to al-Qaeda and Islamic State seen on the streets. The UN says almost 4,900 people have been killed in the past six months of fighting in Yemen, including 2,200 civilians.
