An Assassination Squad Targeting Pro-Japanese Koreans headed to Fengtian

According to the information that arrived at the headquarters of the Fengtian Citizens Protection Association, more than ten members of an assassination squad organized in Kuandian County, Manchuria, disguised themselves as Chinese and, on the 13th of last month, departed Kuandian traveling on a land route toward Fengtian. Their single-minded goal is said to be to assassinate Koreans of the pro-Japanese kind (Fengtian Telegram).
