Deadly fighting

A total of 190 suspects are being tried in batches over the deadly fighting that raged in Bani Hoshaish, northeast of Sanaa, between March and June last year.

Officials said that the men were followers of Hussein Badr Eddin al-Huthi, who was killed by the army in September in 2004.

The group - which is now led by al-Huthi's brother, Abdul Malak - is based in the northern Saada region and wants to restore the Zaidi imamate that was overthrown in a coup in 1962.

An offshoot of Shia Islam, Zaidis are a minority in mainly Sunni Yemen but form the majority in the north.
