Al-Qaeda in the Arabian Peninsula has taken advantage of the weakness of the Yemeni central government during about a year and eight months of anti-government demonstrations to expand their presence in the impoverished country.
Al-Qaeda loyalists have carried out a spate of deadly attacks against Yemeni security forces since Ali Abdullah Saleh's successor, President Abdrabuh Mansur Hadi, came to power in February 2012.
In May, the Yemeni military launched an all-out offensive and retook a string of towns in Abyan province, where al-Qaeda loyalists had established themselves.
At least three Yemeni soldiers have been killed and six others injured after a roadside bomb struck a security convoy in the southeastern province of Hadramout.
The bomb went off as a three-vehicle convoy passed through the Huwaysh neighborhood of Mukalla city - situated 536 kilometers (333 miles) south of Sana’a - on Sunday, Xinhua news agency reported.
A local security official, speaking on condition of anonymity, said the explosive device was planted on a main road near a police station and was apparently detonated by remote control.
He added the blast targeted convoy of Colonel Abdulwahab al-Waeli, head of Central Security in the city.
“All of the high-ranking military officials escaped the bombing safely and unharmed ... The injured were rushed to a hospital, and some remained in serious condition," the security official said.
There was no immediate claim of responsibility. However, security sources accused members of the al-Qaeda terrorist network for masterminding the attack.
