No sabotage groups have been spotted in Ukraine's Vinnytsia region, where ammunition explosions began at military depots late on September 26, and no one has been detained or has escaped, Ukrainian Chief Military Prosecutor Anatoliy Matios said.

"The investigation has not recorded the presence of any sabotage groups, mentioned by Facebook and others... in the territory of Vinnytsia region. There is no information about that. Second: the investigation, which started to work an hour and a half after the explosions began, has not confirmed any information about drones... There have been no groups, about which the defense minister's advisor has spoken, no sabotage and reconnaissance groups or those who were detained or escaped," Matios said at a press briefing in Odesa on Thursday.
