The first Soviet communications satellite, Molniya-1 No.2, is launched at 05:00 UTC, on a Molniya 8K78 carrier rocket, from Site 1/5 at the Baikonur Cosmodrome. A motor circuit in the servo controlling the core stage throttle failed 104 seconds into the flight, resulting in the throttle becoming jammed closed and the fuel supply to the engines being stopped. Prior to the release of information about its mission, NASA had incorrectly identified the launch of Molniya-1 No.2 as a failed attempt to launch a Zond spacecraft on a circumlunar technology demonstration mission, and assigned it the placeholder designation Zond 1964A.

Keith Bennett, 12, is abducted by Myra Hindley and Ian Brady. Bennett vanished on his way to his grandmother's house in Longsight. Hindley lured him into her Mini pick-up, in which Brady was sitting, by asking for help in loading some boxes, after which she said she would drive the boy home. She drove to a lay-by on Saddleworth Moor, and Brady went off with Bennett, supposedly looking for a lost glove. Hindley kept watch, and after about 30 minutes Brady reappeared, alone and carrying a spade that he had hidden there earlier. When Hindley asked how he had killed Bennett, Brady said that he had sexually assaulted the boy and strangled him with a piece of string.
