At least 70 people have been killed in fierce new battles this week between security forces and Shi'ite rebels in northwestern Yemen, bringing the toll to at least 170 killed since fighting broke out last month.
News reports say both sides have suffered casualties. The fighting follows failed government mediation efforts with the rebels.
Government officials blame Badr el-Deen al-Hawthi for the new violence. He is the father of renegade cleric Hussein al-Hawthi, who was killed in September by government forces three months after he started a rebellion in the mountainous northwest.
The government accuses the dead cleric of forming an illegal armed group and inciting anti-American sentiment. Yemen joined the U.S.-led war against terrorism after the September 11, 2001 attacks.
