Hamas has chosen Dr. Abdel Aziz Rantisi as its new leader to replace Sheik Yassin who was assassinated by Israeli forces on Monday. Rantisi is widely seen as a hardliner within Hamas and is considered to be one of the seven founders of the organization. Last year he opposed the group’s declaration of a cease-fire. He told supporters yesterday “The door is open for you to strike all places, all the time and using all means.” Another Hamas leader suggested in an interview that Israeli Prime Minister Ariel Sharon will now be targeted for assassination. Meanwhile President Bush appeared to have approved of the assassination of Yassin. In a brief meeting with reporters Bush said Israel has a “right to defend herself from terror. ”
