At least 13 soldiers and 13 suspected Al Qaeda militants were killed in an attack on an army base in the southern province of Abyan on Friday, medical and military sources said.
Two militants wearing army uniforms drove an explosives-laden car into the military base, killing themselves and 10 soldiers and injuring 15 other soldiers, a military official said.
Moments later, a group of militants attacked the base from the sea and 11 more militants and three soldiers were killed in the fighting that followed.
Violence has intensified in Yemen in recent weeks. The United States, wary of the growing power of Al Qaeda, has stepped up drone strikes on suspected militant positions and militants have increased attacks on army targets.
