"Eight Al-Qaeda militants were killed and others wounded" when army forces "foiled their attack" against a military post near Bajdar on the outskirts of the provincial capital Zinjibar, the ministry's website 26sep.net said.

On Monday, fierce clashes killed at least 21 people, including 18 Al-Qaeda militants, near Abyan's town of Loder, which jihadists are trying to capture.

The army has been battling Al-Qaeda militants, who have renamed themselves as the "Partisans of Sharia" (Islamic law), for control of Zinjibar for nearly a year.

The jihadists have expanded their control over Yemen's lawless southern and eastern provinces, taking advantage of a weakened central government in Sanaa and months of political upheaval.

The extremists intensified their attacks on the security forces after President Abdrabuh Mansur Hadi took office in February pledging to hunt down the militants.
