It was learned the next day that Idi Amin was, in fact, not working to free the hostages. He was working to support the PFLP. This caused other problems for the rescue mission. They now had to worry about the Uganda military at the airport. A large number of the hostages were released on July 1st. The hijackers still held 106 passengers who were all Israeli or Jews. The hostages who were freed were flown to Paris and London. The government of Israel said that they would free the prisoners held in Israel. Because of this, the hijackers agreed to not start killing the hostages until July 4th. Lt Col Yonatan Netanyahu was put in charge of the Israeli mission to free the remaining hostage. Training began the next day for the mission. It was done using information they had gotten from the released passengers. An old home movie taken in Entebbe was used to show them more about the layout of the airport.
