DERA ISMAIL KHAN, Pakistan (AP) — A suspected U.S. missile strike killed at least six people Wednesday, hours after the top U.S. military officer told Pakistani leaders that America respected Pakistan’s sovereignty amid a furor over American strikes into Pakistan’s northwest. Two Pakistani intelligence officials told The Associated Press that several missiles hit a compound in the South Waziristan tribal region early Wednesday evening. Both officials spoke on condition of anonymity because they are not authorized to speak openly to the media.
