WASHINGTON (AP) _ Retaliating 13 days after the deadly embassy bombings in East Africa, U.S. forces attacked alleged terrorist camps in Afghanistan and a chemical plant in Sudan on Thursday. ``Our target was terror,'' President Clinton declared. ``Our mission was clear.''

The president said he acted to ``counter an immediate threat.''

Acting on intelligence information that he said pinpointed ``one of the most active terrorist bases in the world'' and an industrial plant that made agents for chemical weapons, Clinton said he ordered the attacks not only in response to the Aug. 7 embassy bombings but also to pre-empt more planned terrorist attacks on Americans.
