Bowing to international pressure, Indonesia said it will investigate an army shooting in East Timor that may have killed up to 115 people. Witnesses said troops fired on hundreds of mourners Tuesday in the regional capital, Dili. The marchers, in a show of defiance against Indonesian rule, were marking the death of an East Timor activist in riots two weeks ago. "We regret what happened, but it must be realized that they (fighters against Indonesian rule) are brutal," Indonesian armed forces commander Try Sutrisno said in Jakarta. "We will investigate the case."
