Military officials and tribal leaders in Yemen say at least 85 people have been killed in clashes between Shiite rebels and Islamist tribesmen supported by national army units in one week.

The officials said Friday that 11 soldiers were among those killed in the ongoing battles between Shiite Hawthi rebels and tribesmen from the Islamist Islah Party based in the city of Amran, northwest of the capital, Sanaa.

Officials said fighting has blocked the road between Sanaa and Amran and expanded to the outskirts of Sanaa itself.

Local officials in Amran said army units supporting Islamist tribesmen have cordoned off the city to block Hawthi advances.

All officials spoke on condition of anonymity because they were not authorized to brief reporters.
