The week began on a tragic note in Waco, Texas, where four federal agents were killed, along with at least 10 members of the Branch Davidian sect, when the agents tried to arrest the group's leader on weapons charges. Sunday also marked the death of veteran actress Lillian Gish, at age 99. In New York, workers scrambled to clean up debris and repair damage from the bomb that exploded in the World Trade Center. Meanwhile, U.S. Marines continued to provide relief to starving Somalis. On the lighter side, three babies appeared to be enjoying themselves during a diving lesson in Bonn, Germany. And in Troy, N.Y., a woman had a frosty surprise after a water main burst, encasing her car in 4 inches of ice.
