　　美发动大规模清剿 逮捕150名黑手党嫌疑犯

　　Federal authorities in the United States have made 150 arrests in what the US Attorney General Eric Holder called the largest-ever single-day operation against the mafia. Those detained include prominent members of at least six organised crime families. They face charges ranging from extortion to drug dealing and murder. Mr Holder said it was part of an ongoing battle against the mafia.

　　“Today’s arrests mark an important and encouraging step forward in disrupting La Cosa Nostra operations. But the reality is that our battle against organised crime enterprises is far from over. This is an ongoing effort and it must and will remain a top priority to all of us in law enforcement. Members and associates of La Cosa Nostra are among the most dangerous criminals in our country.”

　　Suicide bomb attacks near the Iraqi city of Karbala have killed at least 50 people and injured many more. Jim Muir reports from Baghdad.

　　The Karbala bombings came despite very stringent security measures to protect the many hundreds of thousands of Shiite faithful making their way to the city on foot from all over the country in a pilgrimage that reaches its climax early next week. Even before that, the earliest bit of attacks had prompted questions here about the effectiveness of security arrangements, not just for pilgrims, but /even for the security forces themselves increasingly targeted as American forces withdraw.

　　胡锦涛主席访美 称中国无意推动武器备战

　　The Chinese President Hu Jintao says China has no interest in pursuing an arms race, nor exerting military dominance over other nations. Speaking at a business forum in Washington, Mr Hu said there was no need for the US to see China as a threat. Paul Adams reports.

　　President Hu used his lunch-time speech to drive home his message that America should not see China as a dangerous rival. “We do not engage in arms race,” he said,”we are not a military threat to any country.” He described Tibet and Taiwan as core Chinese interests, but did not add the South China Sea to this list, suggesting a degree of flexibility on an issue that has been a recent source of tension. Earlier, President Hu swapped the military bans at state banquet at the White House for the rather more combative atmosphere of Capitol Hill. Members of Congress raised a number of familiar concerns including human rights, efforts to contain North Korea, safeguarding intellectual property and the need for a level playing field in international trade.

　　新调查表明全球天然气存储量是预期的两倍

　　A new estimer says there may be twice as much natural gas available in the world as previously thought. The International Energy Agency said new techniques to extract gas from previous inaccessible rock formations could extend the global reserve for more than 250 years. Roger Harrabin reports.

　　A few years ago, the world looked likely to enjoy natural gas for 60 years with maybe a further 60 engineers could access all known supplies. Then came a technological breakthrough in the United State, where firms found a way to free gas previously trapped in shale rocks. It made the US the world’s top gas producer in 2009. Engineers worldwide now want to recover more so-called unconventional gas from coal beds and other rocks where it’s currently trapped.
