After western sources already indicated failure during an early part of flight,
the North korean State press agency KCNA now also acknowledges failure to reach
orbit, indicating a problem with the second stage as the cause. More precisely:
"losing thrust due to the abnormal starting of the second-stage engine after the
separation of the first stage during the normal flight"

Yonhap indicates the crash site (with what appears to be a rocket stage
recovered) as "200 km west" of Eocheongdo island:

That would match well with area A from Navigational Warning HYDROPAC 1779/23,
the splash-down zone of the first stage (see map:

stage failed to ignite, both the spent first stage and the stage two/three and
payload stack could have ended up here.

The KCNA report states that they used a new rocket, "Chollima-1", and names the
payload as "Malligyong-1", which if Google Translate doesn't fool me means
something like "Grand View-1".
