Prof. Noam Chomsky who has been very critical of Israel's policies for many years, particularly from the first Lebanon war onwards, yesterday was denied entry at the Allenby Bridge by the Israeli authorities. He was on his way from Amman to Ramallah, where he was scheduled to lecture at Bir Zeit University about American foreign policy. His own account is that it seems he was expected, because he was, quite respectfully, asked to follow a young man, who seemed somewhat embarrassed at having to do this, for questioning.
