South Korea's Yonhap news agency says North Korea has fired what appears to be a powerful new mid-range missile from its east coast. The report couldn't be immediately confirmed.

The agency cited the Joint Chiefs of Staff as saying Wednesday's firing appears to be the latest attempt to launch a Musudan missile, whose potential 3,500-kilometer (2,180 mile) range puts U.S. military bases in Asia and the Pacific within its striking distance.

South Korean officials say the last four launches have failed. It was unclear what happened in the latest firing.

In April, North Korea attempted unsuccessfully to launch three suspected Musudan missiles. All exploded in midair or crashed, according to South Korean defense officials. Earlier this month, North Korea had another missile launch failure.
