During several confidential meetings with Konoha's Herald and the Cloud's Raikage, the Konoha Cloud Squadron assigned to defend the Herald were taken out by a unknown third party, but it is believed a spy was inserted by either Cloud or Konoha to intercept the secret intel. Seven men were massacred in total, some from each side, but one was found alive and the Herald went missing. This altercation has driven a wedge between Konohagakure and Kumogakure, and now the two reproach each other.
