On 15 September 2006, four militants attempted suicide attacks on two different oil facilities in Yemen. Two militants each driving car bombs attempted to target an oil storage facility at the Canadian-Yemeni Dhabba Oil Terminal in Hadhramaut governorate, but their vehicles exploded prematurely after security opened fire on them, killing a guard. Another two militants tried car bombing the Safer oil refinery in Marib governorate shortly after, though they too were killed before their vehicles could reach the target. The attacks were claimed by al-Qaeda in Yemen (AQY).
