He's one of the highest-profile former regime figures to flee to the landlocked African nation. Al-Saadi, the fugitive ruler's 37-year-old son, entered Niger with nine other people, says Niger Justice Minister Amadou Morou. The vehicles were traveling south toward the outpost of Agadez, where other fleeing Libyan loyalists are believed to be holed up in a hotel. ___ YEMEN Two Yemeni soldiers are killed and four wounded by a roadside bomb blast in southern Yemen as government forces battle for control of a key city held by al-Qaida linked militants for nearly four months. Yemeni government forces, backed by the U.S. and Saudi Arabia, are confronting fighters, some with links to Yemen's al-Qaida branch, in Zinjibar, the capital of Abyan province. The drive by Yemeni security forces into Zinjibar marks their first major advance on the city since May. ___ EGYPT Egypt's military ruler and one-time confidant of Hosni Mubarak fails to attend a court session that was expected to bring highly anticipated testimony about the ousted president's alleged role in the death of protesters and possibly offer insider revelations about the regime's final days. The no-show by Field Marshal Mohammed Hussein Tantawi is a major disappointment for Egyptians seeking to have the reckoning over the bloodshed reach to the highest levels. It also could reflect hesitation by Mubarak's former allies to face him in court and possibly air embarrassing secrets.
