A car rigged with explosives and carrying five men pulled up to a military checkpoint in the Yemeni district of Mudiyah in Abyan, military officials said.
Armed with explosive belts, four attackers were killed by soldiers after they failed to blow themselves up in front of the security headquarters in Mudiyah, Officer Fawaz al-Shabhi said.
The fifth man, a suicide-bomber, then detonated his explosive in the vehicle outside the checkpoint, killing four soldiers and injuring around ten others from the Yemeni army.
"At first a suicide-bomber detonated a car filled with explosives near the headquarters of the Yemeni troops in Mudiyah district of Abyan province, making way for a number of attackers to start their assault," a military official said on condition of anonymity.
Shabhi meanwhile stressed that the security situation is under control in Mudiyah, and that the failed terrorist operation came in retaliation to heavy blows received by these groups in all districts of the governorate.
He said that the military operations will continue until all the areas and cities of Abyan are declared free of terrorist elements.
Military campaigns to combat terrorism in Abyan, backed by Arab coalition forces, were launched in late July and succeeded in defeating terrorists in Abyan, where 90 percent of the cities were under the control of Yemeni security forces.
