quoting partially

0Hi,02br
02br
00I was looking at YAHOO! NEWS and saw what seem to be instances of quoting partially. Can you tell me how to do that? What would be the full quotes?02br

00All that, combined with a strategic influx of U.S. troops last year, has "opened the door to a major victory in the broader war on terror," Bush said. -- Why did the quote has been made in the middle of a verb tense? What could be the full quote? Why did not quote using a full quote -- it does look to make not much difference in terms of the length of the quote? 02br

00In a different news piece:02br
02br
00I saw this sentence in what seems to be a report on what the ex-chief weapons inspector for the U.N. said:02br
02br
00In his comment piece, he said the war was a "setback in the world's efforts to develop legal restraints on the use of armed force between states" and added that in 2003, "Iraq was not a real or imminent threat to anybody."02br

00Note: I am not taking any political stand on this hot political issue but only using sentences to ask grammar questions. 0-
