SANAA - Yemeni government forces detained 10 al-Qaida-linked fighters on Friday, a security source said, after an attack in a town that underscored the security challenges of next week's presidential election.
Separately, oil pipeline workers returned to work after a 10-day strike which had shut down oil exports, Yemeni officials and Norwegian energy firm DNO said.
On Wednesday, Islamist militants shot dead a military officer and an election official in the town of Baydah, about 130 km (80 miles) southeast of the capital Sanaa.
The militants opened fire on a car carrying Khaled Waqaa, the leader of a brigade of the elite Republican Guard, killing him as well as the head of Baydah's election committee, Hussein al-Babli, his son and two soldiers. Ten people were wounded.
