Singapore has arrested a British author as part of a criminal defamation investigation related to his book on the city-state's death penalty policy, police said Monday.

Alan Shadrake, 75, was in Singapore to promote the book and was arrested Sunday, police said in a statement.

He hosted an event Saturday promoting "Once a Jolly Hangman: Singapore Justice in the Dock."

Police said they arrested Shadrake based on a complaint by the government's Media Development Authority and were investigating him for other offenses. They declined to give details.

The attorney-general's office is also seeking contempt of court charges against Shadrake because statements in the book allegedly impugn the impartiality, integrity and independence of the judiciary, a spokeswoman said. She spoke anonymously in line with the attorney-general's office policy.

An Iranian opposition group has won a round in its long legal fight to get the State Department to stop classifying it as a terrorist organization.

A federal appeals court on Friday ordered the State Department to reconsider its decision to keep the People's Mujahedeen Organization of Iran on its list of foreign terrorist organizations. The designation prohibits groups from raising money and obtaining other support in the United States.

The court said the U.S. government must give the Iraq-based group a chance to respond to claims that it continues to engage in terrorist activity or at least retains the capability and intent to do so. The government also maintains a file of secret information that it says supports the continuing terrorist designation. Friday's ruling did not address the classified material.

The People's Mujahedeen has argued that it stopped military operations against the Iranian regime and renounced violence in 2001, and handed over its weapons to U.S.-led forces after the ouster of Saddam Hussein in Iraq in 2003.

The European Union dropped the People's Mujahedeen from its list of banned terrorist groups last year.

A British court fined five companies a total of 9.5 million pounds ($14.6 million) Friday for a massive 2005 explosion at a U.K. oil depot that sent a huge smoke plume drifting across the European continent.

Total UK, a subsidiary of French oil company Total SA, was found liable for negligence and ordered to pay most of it — 6.2 million pounds ($9.5 million).

The explosion at the Buncefield oil depot, about 25 miles (40 kilometers) north of London, was triggered when tens of thousands of gallons of gasoline were released in a huge vapor cloud. The blast injured 43 people, caused more than 1 billion pounds in damage and registered a magnitude 2.4 on earthquake monitors.

The explosion was the costliest industrial disaster in British history, Britain's Health and Safety Executive said Friday. Worse casualties were avoided only because the explosion took place early Sunday morning when few people were at work.

Judge David Calvert-Smith said the companies involved — Total UK Ltd., British Pipeline Agency Ltd., Hertfordshire Oil Storage Ltd., TAV Engineering Ltd. and Motherwell Control Systems 2003 Ltd. — had shown "a slackness, inefficiency and a more or less complacent attitude to safety."

He said the problems at the site were so serious that the disaster could have happened "at almost any hour of any day" and said it was just "short of miraculous" that more people were not injured.

A Guantanamo Bay prisoner has been transferred to his homeland of Yemen, the U.S. Defense Department announced on Tuesday, after a U.S. district court ordered the longtime detainee's release.

The release of 26-year-old Mohammed Odaini after eight years at Guantanamo Bay was an exception to the Obama administration's freeze on prisoner transfers to the turbulent country after the failed attempt to blow up a Detroit-bound airliner on Christmas Day. Al-Qaida in the Arabian Peninsula has claimed responsibility for the failed attempt.

"The suspension of Yemeni repatriations from Guantanamo remains in effect due to the security situation that exists there. However, the administration respects the decisions of U.S. federal courts," the Pentagon said in a statement.

Yemen, a poor country with a weak central government on the southern tip of the Arabian Peninsula, has struggled to confront a growing al-Qaida presence.

American worries about Yemen's ability to fight al-Qaida heightened last year after several Yemeni detainees who had been released from Guantanamo Bay in Cuba resurfaced as leaders of an al-Qaida offshoot. Those concerns deepened in the wake of the failed Christmas attack.

Immigration to rich countries dropped during the global economic crisis, reversing five years of annual increases as the demand for labor fell, the Organization for Economic Cooperation and Development said Monday.

A report showed that 4.4 million people migrated to the OECD's 31 member countries — the world's most developed economies — in 2008. That is a drop of about 6 percent from the year before.

The fall reverses five years of annual increases of 11 percent, the OECD said in its International Migration Outlook 2010.

National data suggest that international migration fell again in 2009.

Unemployment among male immigrants has risen more than among native counterparts because many immigrants worked in industries badly hit by the crisis, such as construction, hotels and restaurants, the OECD said. Still, few are returning home, it said.

In some countries, employment of female immigrants has risen as women take jobs to make up for lost income of their unemployed spouses, it said.

Germany condemned Wednesday the jailing of a 79-year-old prominent human rights lawyer by a Syrian court and demanded his immediate release.

The German government's human rights commissioner, Markus Loening, said he was "shocked" by the sentencing of Haytham al-Maleh to three years in prison Sunday on charges of "publishing false information".

"Mr Maleh is considered a leader of the Syrian human rights movement who has committed himself for decades at great personal risk for the protection of human rights in his country," Loening said.

"I call on the Syrian government to comply with its international commitments, in particular in implementing the International Covenant on Civil and Political Rights and, in light of Mr Maleh's advanced age and his precarious health, release him immediately."

Maleh was arrested in Damascus on October 14 last year, and investigated by the military court over articles he had written.

The lawyer had been imprisoned from 1980 to 1986, along with a large number of trade unionists, activists and political opponents, for demanding constitutional reforms.

He has worked with Amnesty International since 1989 and, in 2001, helped to establish the Syrian Human Rights Association, whose activities have been frozen for more than three years.

An American geologist detained and tortured by China's state security agents over an oil industry database was jailed for eight years Monday in a troubling example of China's rough justice system and the way the U.S. government handles cases against its citizens.

Beijing's No. 1 Intermediate People's Court convicted Xue Feng of collecting intelligence and illegally providing state secrets and immediately sentenced him.

Xue's lawyer Tong Wei described the sentence as "very heavy", just short of the maximum 10 years, and said he would confer with Xue over whether to appeal. Xue was also fined 200,000 yuan ($30,000).

The U.S. Ambassador to China, Jon Huntsman, witnessed the sentencing in a show of high-level U.S. government concern about the case. Afterward, the U.S. Embassy released a statement saying it was dismayed and urged China to grant Xue "humanitarian release and immediately deport him."

For Xue, the verdict comes more than six months since the last court hearing and two and a half years after he was detained — a protracted prosecution and pretrial detention that Chinese officials never explained.

Born in China and trained at the University of Chicago, Xue ran afoul of the authorities for arranging the sale of a detailed commercial database on China's oil industry to IHS Energy, the energy consulting firm he worked for that is now known as IHS Inc. and based in Colorado.
