The terrorist organization Hizb ut-Tahrir held an anti-Annapolis rally in Hebron as well as in Nablus, totaling thousands of people.
We don't hear much about Hizb ut-Tahrir in the PalArab territories, but they are a worldwide extremist Muslim organization dedicated to creating a single Islamic state based on Islamic law. (They are also more than a little anti-semitic.) This means that Palestinian Arab statehood is not their goal at all - they make no pretense of wanting a Palestinian Arab state, only a pan-Islamic state that of course involves the destruction of Israel.
The turnout indicates yet again that Mahmoud Abbas has very little influence on his own people, and that Ramallah is pretty much the only Palestinian Arab town that is more secular than Islamist.
Predicatbly, the rallies (which were unauthorized) descended into violence, and a 37-year old Hizb supporter was shot in the heart by those crack Palestinian Arab policemen and killed.
The 2007 PalArab self-death count is now at 585.
UPDATE: Perhaps I spoke too soon - Hizb also held a rally in Ramallah that was broken up by police.
