More than four months after a deadly attack at a sprawling allied base in Afghanistan that killed two U.S. Marines, there are lingering questions about how it happened.

The economy shrunk in the fourth quarter — for the first time in three years — and one of the critical reasons was a drop in defense spending.

Those decisions about U.S. troop levels will have an impact on the lives of people in Afghanistan, especially in places where the Taliban insurgency remains active, like Kandahar. Kandahar is, of course, the birthplace of the Taliban movement. And to find out more about what Afghans are thinking about the U.S. drawdown, we reached Ehsan Ullah Ehsan, who is the director of a school in Kandahar, the Kandahar Institute of Modern Studies, which has offered, for several years, instruction to girls in computers, English and business management.

Robert Siegel talks to Ofeibea Quist-Arcton and Tom Bowman about the U.S. fight against terrorism in Africa, where the number of Islamist militant groups is on the rise — some with close ties to al-Qaida.

The number is a larger estimate than has previously been reported. The Syrians loaded the weapons with the chemical agents in the past several weeks, the officials say.

Those preparations raise fears that the fighting against rebel forces could enter a new and more troubling phase, according to the officials, who requested anonymity.
