In Afghanistan, four Marines died Sunday in two separate roadside bomb blasts. On Friday, eight British troops died. Overall, 192 foreign troops have been killed so far this year in Afghanistan — a 40 percent jump from the same period last year. More British troops have now died in Afghanistan than in Iraq. Meanwhile, President Obama has ordered national security officials to look into allegations that the Bush administration resisted efforts to investigate a CIA-backed Afghan warlord over the killings of at least 2,000 Taliban prisoners in 2001. We’ll have more on this story later in the broadcast.
