國安局監控美國人網絡通訊多於外國人

A report in a major U.S. newspaper says when the National Security Agency intercepted the online accounts of legally targeted foreigners over a four-year period, the agency also collected the conversations of nine times as many ordinary Internet users, both Americans and non-Americans.

The Washington Post, in a story posted on its website late Saturday, says nearly half of the surveillance files contained names, email addresses or other details the NSA marked as belonging to U.S. citizens or residents.

The huge trove of intercepted documents was provided to the Post by former NSA analyst Edward Snowden, who fled the United States and is now living in Russia.

The newspaper says there were "discoveries of considerable intelligence value" in the intercepted messages, including revelations about a secret overseas nuclear project, double-dealing by "an ostensible ally," an unfriendly power's military calamity, and the identities of aggressive intruders into U.S. computer networks.

Officials in Washington have made no immediate comment about the report.美國一家主要報紙說，美國國家安全局在合法截獲一些外國人網絡通訊的4年期間，也收集了多達9倍的普通美國和非美國因特網使用者的通訊紀錄。

華盛頓郵報星期六晚間在網站上發表的一個報道說，幾乎一半的截獲資料包括姓名、電郵地址或者其他信息，國安局標明是屬於美國公民或居民的。

逃離美國、目前居住在俄羅斯的前國家安全局分析員斯諾登，向華盛頓郵報提供了這些截獲文件的巨大的情報數據。

郵報說，在被截獲的信息中發現了非常有情報價值的通訊，包括揭密一個祕密海外核項目、一個“表面盟國”的兩面派做法、一個非友好強國的軍事災難，以及侵入美國電腦系統的咄咄逼人黑客的身份等等。

華盛頓的官員還沒有立即對華盛頓郵報的這篇報道發表評論。
