Yemeni prosecutors brought 16 suspected al-Qaida members to trial Wednesday on terrorism charges that include an attack on the American embassy and killings of foreigners in Yemen. The prosecution alleged the suspects, 14 Yemenis and two Syrians, formed an al-Qaida cell that masterminded a spate of attacks. Some of them are accused of firing a volley of mortars at the US embassy compound in March 2008. The mortars hit an adjacent girls high school instead, killing a Yemeni guard and wounding dozens of schoolgirls. The charges also include 23 other terrorists acts, such as the January 2008 killing of two female Belgian tourists, attacking a foreigners' residential compound in Hadramout province and clashes with police in which an al-Qaida militant leader was killed.
