South Korea has warned North Korea not to go ahead with a planned spy satellite launch, saying Seoul could suspend an inter-Korean peace deal and resume frontline aerial surveillance in retaliation.

North Korea failed in its first two attempts to put a military spy satellite into orbit earlier this year and did not follow through on a vow to make a third attempt in October.
