South Korea and the United States stepped up their intelligence and surveillance status for North Korea’s possible provocation although the two Koreas started inter-Korean high-level talks on Saturday.
 
The South Korea-U.S. Combined Forces Command on Sunday raised their five-level Watch Condition alert system, or WATCHCON, from level three to level two.
 
The South Korean military is closely watching the movements of North Korean troops and mobilizing all available reconnaissance assets.
 
The South Korean military and U.S. troops also remain ready to immediately respond in case the North attacks South Korea’s loudspeakers on the border.
 
The South Korean military is said to have detected 72-point-two millimeter field guns, which were used for the North’s artillery provocation on Thursday, being deployed at some parts of the front-line areas. Some North Korean soldiers were also observed conducting a firing drill.
