Before today:
n recent months, the number of insider attacks has dropped significantly as protective measures were continued and fewer international troops worked directly with Afghan forces.

In June, two coalition servicemembers were wounded in a suspected insider attack at a police station. In February, two U.S. Special Forces soldiers were killed and four others were wounded when a suspected member of the Afghan security forces opened fire on them. And in April, an Associated Press journalist was killed and another seriously wounded when a police commander opened fire on them inside a heavily guarded Afghan security forces base in eastern Afghanistan.
