Suspected Mastermind in Mumbai Attack Pleads Not GuiltyDavid Coleman Headley pleaded not guilty before U.S. District Judge Harry Leinenweber on Wednesday. It’s alleged Mr. Headley traveled to India and Pakistan repeatedly over nearly two years to videotape targets and brief plotters for the 2008 attack. This Chicago man is charged for helping to lay the groundwork for the 2008 terrorist attacks in Mumbai that killed 166 people. Headley, a 49-year-old Pakistani-American, waived his right to be indicted by a grand jury. He has been charged with 12 counts in connection with the Mumbai attacks.

Missing Americans Detained in AfghanistanPakistani police on Wednesday arrested five American men believed to have gone missing from the Washington, D.C. area last month, officials from both countries said. But two U.S. officials familiar with the case said the five are believed to be young men from the Washington area who went missing at the end of November.

The men were picked up in a raid on a house in Sarghoda in the eastern province of Punjab, police officer Tahir Gujjar said. The men are of Pakistani descent, one is of Egyptian descent, and the other is of Yemeni heritage. Regional police chief Mian Javed Islam said the men were between the ages of 18 and 20 and had spent the past few days in the city, near an air base about 125 miles south of Islamabad. The Americans are being questioned. It is still too early to discuss the reason for the detentions.

Emissions Cuts Could Hurt Oil RevenueMany of the world’s fastest-growing oil consumers are under pressure to cut carbon emissions. As a result, big petroleum-producing states are beginning to worry over a long-term drop in crude-oil revenue. For many years, oil-producing states have been concerned about rich nations like the U.S. cutting back on energy consumption through conservation or turning to alternatives such as ethanol and other biofuels. A cut in carbon emissions could cause a long-term drop in crude-oil revenue. But Saudi Arabia and other big Gulf states now fear that emerging markets like China, who is the biggest driver behind the growth in world oil consumption, may also cut crude demand as dozens of countries meet in Copenhagen to try to make a pact to reduce carbon emissions.
