双语新闻：俄罗斯研究威胁冬奥会的激进组织视频 Russians Study Militant Video Threatening Olympics

俄罗斯安全人员正在研究一个伊斯兰激进组织发表的录像。该组织宣称为上月伏尔加格勒的自杀爆炸负责，并威胁要袭击即将在索契举行的冬奥会。

星期日，在达吉斯坦人口以穆斯林为主地区的一个激进组织在网上发表了这段录像。不清楚这段录像的制作时间。

在录像中，两名讲俄语的男子警告普京总统，要他准备在索契冬奥会上接受一份他们所谓的“礼物”。这段录像说，这两人是自杀炸弹爆破手，他们上月在伏尔加格勒发动袭击，炸死34人。这种说法没有得到独立消息来源的证实。
美国军方星期一说，将随时为正在准备索契冬奥会安全事务的俄罗斯政府提供海空支持。五角大楼发言人发表声明说，美国的支持包括黑海海域的两艘美国海军军舰，如果俄罗斯提出要求，美国方面愿以任何方式进行磋商。

另外，在索契的酒店工作人员告诉记者，他们看到通缉一名达吉斯坦妇女的告示。告示称那名妇女是22岁的寡妇，她的丈夫是激进分子，去年被俄罗斯安全部队击毙。告示还说，这名妇女可能在索契或周边地区，可能正在策划一次袭击。

Russian security forces are studying a video posted by an Islamic militant group that claims responsibility for last month's suicide bombings in Volgograd, and threatens attacks at the upcoming Olympics in Sochi.

The video was posted online Sunday by a militant group from the predominately Muslim region of Dagestan. It is unclear when the video was made.

In the video, two Russian-speaking men warn President Vladimir Putin to expect what they call a "present" at the Sochi Winter Olympics. The video says the two men are the suicide bombers who attacked Volgograd last month, killing 34 people. There is no independent confirmation of that claim.

The U.S. military said Monday it will make available air and naval support to the Russian government as it makes security preparations for the Olympics. A Pentagon spokesman said in a statement that support including two U.S. Navy ships in the Black Sea will be available, if requested, "for all manner of contingencies" in consultation with the Russian government.

In another development, hotel workers in Sochi tell reporters they have seen wanted posters for a woman from Dagestan. She is described as a 22-year-old widow of a militant killed by Russian security forces last year. The posters say the woman ((identified as Ruzanna Ibragimova)) may be in or near Sochi and could be planning an attack.
