Sources quoted by Radio Israel claim that the Israeli military is threatening to "use force if necessary" to stop the MV Rachel Corrie as it too attempts to break the siege of Gaza and take humanitarian aid to the territory. Named after the American peace campaigner who was killed by an Israeli armoured bulldozer in 2003, the Irish-registered ship was late joining the Freedom Flotilla due to mechanical problems. The military sources say that all necessary steps will be taken to prevent the Rachel Corrie from reaching its destination.
