**克里与俄罗斯外长将就乌克兰危机举行会谈**
美国国务卿克里目前在伦敦，将与俄罗斯外长拉夫罗夫就乌克兰危机问题举行会谈。
在美俄两国外交首脑星期五举行会谈之际，作为危机焦点的克里米亚正准备星期日举行全民公投，投票结果可能导致克里米亚脱离乌克兰，加入俄罗斯。
美国和欧盟领导人一直把得到俄罗斯支持的克里米亚全民公投称做“违宪”。克里警告莫斯科，如果俄罗斯并吞属于乌克兰的克里米亚半岛，将产生严重后果。
但俄罗斯官员表示，在亲俄罗斯的乌克兰政府上月垮台后，克里米亚选民有权进行自决。星期四，俄罗斯承认向乌克兰边境附近增派了数千军人和军事装备，准备进行为期两周的军事演习。
在俄罗斯增派部队之前，克里估计俄罗斯可能在克里米亚驻军两万。
Kerry Meeting Lavrov in Another Attempt at Calm in Crimea
U.S. Secretary of State John Kerry is in London for talks with Russian Foreign Minister Sergei Lavrov on the crisis in Ukraine.
Friday's talks come as the Ukrainian region at the center of the crisis -- Crimea -- prepares for a referendum Sunday that could see it break away from Ukraine and join Russia.
U.S. and European leaders have called the Russia-backed referendum "unconstitutional," and Kerry has warned Moscow of serious consequences if it annexes the Ukrainian peninsula.
But Russian officials say voters in Crimea have a right to self-determination following last month's collapse of the pro-Russian government in Ukraine. And Moscow on Thursday acknowledged deploying thousands more troops and military hardware near the Ukrainian border for maneuvers that will continue for two weeks.
The deployment is in addition to the 20,000 troops Kerry estimates Russia may have in Crimea.
**马航班机在失联后数小时内向卫星发送电子脉冲信号**
预计搜寻马来西亚航空公司失联班机的范围星期五将扩大至印度洋，新证据显示这架班机在失联后可能继续飞行了几小时。
未透露姓名的美国官员在介绍调查情况时说，这架波音777客机上星期六从民用雷达屏幕上消失后的几小时内，自动向卫星发送电子信号。
有关官员说，通信卫星接收到微弱的电子脉冲信号，这种信号的设计用途是通报飞机的一般维护状态以及其他数据。
目前还不清楚这些电子脉冲信号能否提供有关失联班机所在位置的信息，而且也不清楚班机在发送信号时是否处于飞行状态。
来自12个国家的船只和飞机的搜寻已经持续了六天。这架班机载有239人，原定从吉隆坡飞往北京。
最初的搜寻集中在泰国湾，这架班机在那里从民用雷达屏幕上消失。马来西亚军方说，可能探测到这架班机偏离航线数百公里，跨越马来西亚半岛到马六甲海峡。
白宫发言人卡尼星期四说，可能要在印度洋广大海域展开新的搜寻行动。印度洋是世界第三大洋，水深远远超过已经搜寻过的海域。
Malaysia Plane Sent Satellite 'Pings' Hours After Vanishing:
The search for a missing Malaysian jetliner expanded toward the Indian Ocean on Friday, as new evidence emerged that the jet may have traveled for hours after it vanished.
Speaking anonymously, U.S. officials briefed on the investigation said the Boeing 777 sent automated electronic messages to satellites several hours after it disappeared from civilian radar Saturday.
The officials said the communications satellites detected faint messages, known as pings, which attempted to relay regular maintenance and other data about the plane's condition.
It is not clear whether the messages can provide information on the plane's location. It is also not clear whether the plane was in the air at the time the messages were sent.
Ships and planes from over a dozen countries have been searching for six days for the Malaysia Airlines plane and its 239 people on board, who were headed from Kuala Lumpur to Beijing.
The initial search focused on the Gulf of Thailand, where the airliner was last spotted by civilian radar. The Malaysian military has since said it may have tracked the plane hundreds of kilometers away, across the Malaysian peninsula in the Strait of Malacca.
On Thursday, White House spokesman Jay Carney said "an additional search area may be opened" in the vast Indian Ocean. It is the world's third largest ocean and is significantly deeper than the other search areas.
