SANAA, Yemen — Yemeni security officials say a national security court has accused three former top military officials, including a nephew of the former president, over negligence for a suicide attack that struck a military parade and killed more than 90 conscripts.

Officials say the court also Wednesday sentenced five militants to up to ten years in prison for their role in the same May 2012 attack in the capital Sanaa.

The court said the senior officials, including the nephew of former President Ali Abdullah Saleh, were not present during the attack.

Separately, officials say suspected al-Qaida militants killed four soldiers in an attack on a military checkpoint in the southern Hadramawt province.

Officials spoke on condition of anonymity because they were not authorized to brief the media.
