Israel is a "reality" and "there will remain a state called Israel, this is a matter of fact," Hamas leader abroad Khaled Mashaal said in an interview to Reuters on Wednesday. "The problem is not that there is an entity called Israel," he said. "The problem is that the Palestinian state is non-existent." According to the Reuters report, Mashaal said Hamas would defy Western sanctions and refuse to consider formally recognizing Israel until its demand for a Palestinian state was met. Mashaal reiterated Hamas's demands for the creation of a Palestinian state that includes Gaza, the West Bank and east Jerusalem and that Israel accept the right of Palestinian refugees to return to homes lost in the 1967 War and before. In other news, dozens of students blocked traffic at the Glilot junction and at the entrance to Jerusalem on Wednesday as colleges across the country went on strike to protest expected increases to tuition. Students asked passing motorists to contribute a shekel each to the higher education budget, in an effort to emphasize the budget deficit. Students' Union Secretary General Salam Sharkiya said hundreds of drivers contributed to the cause. The protesters were students from 27 colleges across Israel. The national student movement expressed its support for the teachers' unions' protests. Teachers across the country on Wednesday canceled classes for grades 1 and 2, and 11 and 12. The strike is part of the teachers' unions' battle with the treasury for a new collective wage deal. The treasury responded by describing the strike as "unsurprising, and done for reasons only known to the teachers themselves."
