We have much more from Afghanistan tonight, as we wrap up our week of reporting from the war zone.

Today Americans marked the eighth anniversary of the September 11th attacks with memorials that have grown familiar, but no less heartbreaking. U.S. troops in Afghanistan also took time out today to remember the attacks. Meantime, the Pentagon announced that Defense Secretary Robert Gates wants to send as many as 3,000 more troops to Afghanistan.

In the weeks after the 9/11 attacks, support for the Afghanistan invasion was high but support is now waning. On Capitol Hill today, Democrats expressed doubts about deploying more troops, with Senate Armed Services Chairman Carl Levin saying it’s time for a surge of Afghan troops. Tonight, we’ll dig deeper on the pushback.

We’ll also show you how U.S. military doctors are mentoring Afghani doctors on the job. 360 MD Sanjay Gupta spent time at a medical center in Kandahar, where he watched American physicians teaching lifesaving lessons to local doctors. In a country with too few physicians and enormous medical needs, it’s a crucial mission. Sanjay will take us up close.

A short time ago, Anderson filed another reporter’s notebook from the field. If you want to get a sense of what it feels like to serve in this battle zone—the dust, the heat, the isolation—you’ll understand after watching Anderson’s report.

We’ll also have the latest on a missing Yale graduate student. Annie Le was last seen Tuesday morning, entering a campus building. A security camera caught her on tape. The 24-year-old doctoral student in pharmacology planned to get married on Sunday, but has not contacted her family, co-workers or friends. Randi Kaye has the latest on the investigation.

See you at 10 p.m. ET.
