ADEN - A roadside bomb in Yemen's capital Sanaa killed three soldiers and injured two others during a security patrol early on Saturday, a security official said.
The official said the blast targeted a car in Sanaa's al-Hasaba district, a center of opposition to former Yemeni leader Ali Abdullah Saleh who was ousted early last year.
The official, who requested anonymity, said it was unknown who carried out the attack.
Yemen is the poorest Arab state with a third of the population living on less than $2 a day. It faces a Shi'ite uprising in the north, an Islamist insurgency in the south and east, a southern separatist movement and splits in the military.
