国际英语新闻：Obama in damage control over war leak

WASHINGTON, July 27 (Xinhua) -- U.S. President Barack Obama on Tuesday tried to control the damage of the leak of over 90,000 classified reports about the Afghanistan war, saying the documents don't reveal anything new.

Speaking at the White House, Obama said he's "concerned about the disclosure," but "these documents don't reveal any issues that haven't already informed our public debate on Afghanistan."

"They point to the same challenges that led me to conduct an extensive review of our policy last fall," argued Obama.

The leak, made public by website WikiLeaks, involved reports written by U.S. soldiers and intelligence officers in Afghanistan mainly describing lethal military actions involving the U.S. military. Put together, they amount to a blow-by-blow account of the war over the last six years, which has so far cost the lives of more than 1,000 U.S. troops.

The U.S. government has already launched an investigation as to the origin of the leak. Pentagon spokesman Geoff Morrell said Bradley Manning, a 22-year-old private charged in an earlier leak to WikiLeaks, was named a "person of interest" in the new investigation.

Obama said the leak won't change the war strategy. "We have to see that strategy through," he said.
