Foreign and Indian guests holed up by militants in Trident-Oberoi in Mumbai were being evacuated room by room on Friday. Well-dressed guests, some dragging their suitcases, emerged from the Trident-Oberoi hotel and were escorted into waiting buses and cars, as the end of the siege appeared imminent. Scores of others were trapped in the fighting or were being held hostage. Police said 279 people were wounded.
