General Yiri was a Trelonian who lived sometime prior to 2370.
When circumstantial evidence showed up that Yiri's brother was a traitor to the Trelonian government, Yiri had him executed. This decision was condemned by Doctor Bashir in a conversation with Elim Garak, who thought that Yiri was right because he protected the state rather than his brother. (DS9: "Profit and Loss")
