The renewed fighting erupted in the same area where eight people -- six tribesmen and two soldiers -- were killed three days ago, police said.
"Four soldiers and a tribesman were killed in new fighting today," a police official said, declining to be named. Tribesmen in the mountain village of Labus regard the presence of troops in the area as a provocation.
Another tribe attacked troop reinforcements heading towards Labus, but details of casualties were not immediately known.
Yemen, a deeply tribal country on the Arabian Peninsula, has been the site of deadly protests since late January calling for the ouster of President Ali Abdullah Saleh.
The protests have led to defections and clashes within the army. But the Republican Guard, headed by Saleh`s son Ahmed, has remained loyal.
In addition to anti-regime protests, Yemen has been battling a secessionist movement in the south, a Shiite rebellion in the north, and an Al-Qaeda resurgence on its soil. (*)
