At least one soldier was killed and three others wounded in an ambush, believed to be by suspected Al-Qaeda militants, in Yemen's southern province of Abyan.
Eyewitnesses said that Al-Qaeda militants attacked on Sunday a patrol vehicle in Zenjabar. No more details were reported.
Two days ago four soldiers were killed in an attack by suspected Al-Qaeda militants in Yemen's southern province of Hadramout.
Analysts said that Al-Qaeda in the Arabian Peninsula, AQAP, has increased its attacks against Yemen's forces.
The Yemen-based Al-Qaeda in the Arabian Peninsula (AQAP) has a strong presence in southern Yemen as a series of terrorist attacks against security and army forces took place in the country's southern and eastern provinces since 2009.
A recent statistic by the Interior Ministry late last year showed that a total of 178 security force members were killed in 2010, mostly in combats against Al-Qaeda militants, and another 852 were injured.
The ministry last December said it planned to establish four counter-terrorism units in different provinces, including Hadramout, to curb the activities of resurgent Al-Qaeda wing.
