SANAA, May 24 (AP): With chains and locks, a powerful Yemeni tribe has sealed several government buildings as it lays siege to a vital Sanaa district in fierce clashes with government forces. A medical official says Tuesday that a total of seven people have been killed and 42 others injured since fighters of the Hashid, Yemen's biggest tribe, have engaged in an unprecedented confrontation since Monday with troops of President Ali Abdullah Saleh. The official spoke on condition of anonymity because he was not authorized to speak to the press.
