国军方调查人员正在检查布拉德利•曼宁(Bradley Manning)使用的电脑，以确定他是否是周日“维基泄密”(Wikileaks)上公布的数千份军事文件的消息来源。曼宁是一位美军情报分析员，本月被指控泄漏机密信息。
“维基泄密”上公布的资料全部与曼宁驻扎伊拉克期间的阿富汗战事有关。不过，调查人员正在试图确定他能够获得哪些资料，又传送了哪些资料。
美国国防部发言人拉邦上校(Dave Lapan)说，调查人员正在进行广泛的调查，以便确定资料来自哪里，不过他们承认曼宁是嫌疑人之一。拉邦说，我们正在对他进行仔细的调查。
“维基泄密”周日公布了五年多时间内的数千份美军机密文件。有些信息平淡无奇，有些则有戏剧性的描述，展示了战地人员发来的原始的详细情报报告。其中，文件讨论了平民伤亡问题、巴基斯坦在援助塔利班(Taliban)中的作用，以及阿富汗叛乱分子的军备能力。
“维基泄密”创始人朱利安•阿桑奇(Julian Assange)周一在伦敦的新闻发布会上拒绝就泄漏文件的消息来源的身份及其如何拷贝、泄漏的文件进行置评。当记者问及曼宁时，阿桑奇说，据我们所能确定的，没有人宣称周日“维基泄密”上公布的文件与曼宁有关。
他说，尽管如此，“维基泄密”承诺向曼宁的法律辩护提供资金，如果军方为他指定的法律团队要聘用非军事律师的话，“维基泄密”将提供资金。
阿桑奇说，泄漏文件的消息来源的动机是为了引起人们对若干此类事件的关注。
曼宁的军方辩护团队没有回复记者的置评请求。
7月初，美国军方宣布，将敦促对22岁的曼宁提起刑事指控，罪名是向其电脑传送机密军事信息，并向一个未经授权的消息来源提供国防信息。
这 些指控看起来与“维基泄密”公布于众的一份机密视频的泄漏有关。视频中描述了2007年两名路透社(Reuters)记者等在伊朗的个人被“阿帕奇” (Apache)武装直升机杀害，引发国际舆论一片哗然。4月初，“维基泄密”公布了“附带谋杀”，即一系列与此次袭击事件有关的文件和视频。
“维基泄密”说，一名被称为“我们勇敢的消息来源”的未具名人士提供了这些资料，其中包括激烈枪战场面的视频。
据美国军方的案件纪录，曼宁在驻扎在巴格达东部的一个军事基地时，以不当手段获得了秘密情报，其中包括国务院有关2007年7月军事行动的机密有线电视和视频片断。
Military investigators are checking computers used by Bradley Manning, a U.S. Army intelligence analyst charged this month with leaking classified information, to see if he is the source of thousands of military documents published Sunday by WikiLeaks.
The material released by WikiLeaks relates entirely to the war in Afghanistan, while Pfc. Manning was stationed in Iraq. But investigators are trying to determine what material he was able to get access to and what material he transferred.
Col. Dave Lapan, a Pentagon spokesman, said investigators are looking broadly to determine where the material was taken from, but acknowledged that Pfc. Manning was a person of interest in the investigation. 'He is someone we are looking at closely,' Col. Lapan said.
WikiLeaks Sunday published thousands of secret U.S. military documents spanning more than five years. The information is in part humdrum and also dramatic, showing in raw detail the intelligence reports sent from personnel in the field. Among other things, the documents discuss civilian casualties, Pakistan's role in aiding the Taliban and the weapons capabilities of the Afghan insurgency.
WikiLeaks founder Julian Assange, at a news conference in London Monday, declined to comment on the identity of the source who leaked the documents, or on how the source managed to copy and leak them. Asked about Mr. Manning, Mr. Assange said: 'There is no allegation as far as we can determine' that the documents posted on WikiLeaks Sunday are 'connected to Bradley Manning.'
He said WikiLeaks has nonetheless 'committed funds' to Pfc. Manning's legal defense, offering his military-appointed legal team money in case it wants to hire civilian counsel.
Mr. Assange said the source who leaked the documents was motivated by a desire 'to call attention to a number of these incidents.'
Mr. Manning's military defense team didn't respond to requests seeking comment.
In early July, the U.S. military announced it would press criminal charges against 22-year-old Pfc. Manning for allegedly transferring classified military information to his computer and 'delivering national defense information to an unauthorized source.'
These charges appear to be connected to the leak of a classified video that WikiLeaks released to the public. The video, which depicts the July 2007 killing of two Reuters journalists and other individuals in Iraq by Apache helicopter gunships, provoked an international media sensation. In early April, Wikileaks released 'Collateral Murder,' a package of documents and videos related to the attack.
The organization said an anonymous leaker, credited only as 'our courageous source,' had furnished the materials, which included dramatic gunsight video.
According to a U.S. military charge sheet, Pfc. Manning improperly obtained secret information, including classified State Department cables and video footage of a July 2007 military operation, while stationed at a base east of Baghdad.
