At the American Israel Public Affairs Committee or AIPAX conference this week, it was Iran, not Palestine that dominated proceedings. World leaders may be looking elsewhere, but the clashes at Israeli checkpoints are on the rise. Palestinian prisoners are on hunger strike in Israeli detention centres, and a growing sense of impotence and frustration is fuelling talk of a third intifada.

They will deliver it first, out of courtesy, to the Israeli government, and then circulate it to the international community. Al Jazeera's Paul Brennan reports from the Occupied West Bank.
