Hospital officials in Israel say the American activist Tristan Anderson is now semi-conscious after days under full anesthesia. Anderson was critically injured Friday when Israeli soldiers fired a tear gas canister directly at his head during a weekly nonviolent protest against the separation wall in the West Bank village of N’alin. Anderson underwent brain surgery in an Israeli hospital near Tel Aviv on Saturday. Parts of his right frontal lobe were removed. Anderson is now able to lift fingers on one hand in response to a voice command.
