The IDF this morning began releasing army reservists who had been called up at the end of last week for an anti-terrorism raid into Gaza. The government has now decided to freeze the offensive, officially explaining that there was no point in carrying it out now that the Hamas terrorists had gone into hiding. Some officials said that details of the operation were leaked to the press, thus forcing the postponement. MK Michael Kleiner (Herut) raises a third possibility, saying today that the real reason for the cancellation was \"capitulation to American pressure.\" The offensive was originally planned following the suicide attack in Rishon Lezion on Tuesday that claimed the lives of 15 Israelis.
