Yemeni security officials and tribal elders say fighting has intensified outside the capital, killing at least 30 people in two days.
They said Tuesday that some 25 fighters from both sides were killed in fighting between government forces and Shiite rebels and their allies some 65 kilometers (40 miles) east of Sanaa. Five civilians were also killed.
In the southern port city of Aden, fighting erupted Tuesday night between government forces and al-Qaida fighters after authorities set up roadblocks as part of a security plan.
Yemen's conflict pits a loose array of government-allied forces against the Shiite Houthi rebels and troops loyal to a former president.
The officials, who are neutral in the conflict, and tribal elders spoke on condition of anonymity because they were not authorized to brief reporters.
