SANAA, Yemen (AP) — Three explosions struck Yemen's port city of Aden on Tuesday, including a blast at a hotel that is home to Cabinet members of the country's exiled government, security officials said. The seven-state federation has some 4,000 troops on the ground, a senior Emirati commander said last month, and boasts military hardware including tanks, armored fighting vehicles and attack helicopters. The security officials, who work for Yemen's internationally recognized government, said one explosion rocked the Al Qasr Hotel, where the prime minister and officials reside, while the other two hit a residence and the local headquarters of Emirati troops. Members of the Gulf coalition have been providing security at the luxury hotel, and the Yemeni government officials' presence there makes it a highly symbolic target for the rebels. Yemen has been embroiled in fighting that pits the Shiite rebels known as Houthis and forces loyal to a former president against the Saudi-backed and internationally recognized government as well as southern separatists, local militias and Sunni extremists.
