An aid worker from the United Arab Emirates was shot dead in the southern Yemen city of Aden by unknown gunmen on Saturday, a Yemeni security officer said, in another sign of instability in the port city where Yemen's fragile government is based. "The aid worker was travelling in an armored land cruiser with a group of Emiratis in Aden's Mansora district.
He was shot dead when he exited the vehicle near a store by gunmen pursuing in another car," said the official. A UAE spokesperson was not available for comment. Al Qaeda and Islamic State have both gained ground in Yemen, where a war has been raging for seven months between a Saudi-led military alliance and Houthi militiamen allied to Iran. In a series of suicide bombings on October 6, Islamic State killed 22 people, including several troops from the United Arab Emirates, at the government headquarters in the southern port of Aden and military bases in the city.
