FERGUSON, Mo., Nov 26 (Reuters) - Two FBI agents were shot and wounded at a house in north St. Louis County early on Wednesday, though the incident was "not directly related" to racially charged unrest in and around nearby Ferguson, an agency spokeswoman said. One agent was shot in the shoulder and the other was shot in the leg while assisting local police in executing an arrest warrant, FBI spokeswoman Rebecca Wu said in a brief statement.
