South Korea and the United States said they fired eight surface-to-surface missiles early on Monday off South Korea's east coast, responding to a barrage of short-range ballistic missiles launched by North Korea on Sunday.
The action is a demonstration of "the capability and readiness to carry out precision strikes" against the source of North Korea's missile launches or the command and support centres, South Korea's Yonhap news agency cited the South Korean military as saying.
