On the same day, the civic and public organizations held a news conference demanding the probe into the truth behind the "Cheonan" case.

Meanwhile, the People for Achieving Peace and Reunification of south Korea at a news conference on Sept. 13 urged the U.S. and south Korean authorities to stop hostile actions straining the situation of the Korean Peninsula.
