This seems to confirm Palestinian Involvement FROM SKY NEWs

Palestinians Celebrate Attacks Palestinians gave away sweets in the West Bank city of Nablus to celebrate a series of aircraft attacks on two major US cities.

Several dozen Palestinian youths also gathered in Arab East Jerusalem to celebrate, honking out wedding tunes on their car horns after the attacks levelled the twin towers of the World Trade Centre in New York and struck the Pentagon in Washington. In Nablus, motorists honked their horns and gunmen fired into the air from assault rifles to cheer on the attacks, which unfolded in the space of a few hours and stunned people around the world.

'So happy'

Despite Palestinian President Yasser Arafat condemning the attacks, Palestinians, who have often burned US flags in protests during their 11-month-of uprising against Israeli occupation, celebrated in the streets of Arab East Jerusalem.

"I feel I am in a dream. I never believed that one day the United States would come to pay a price for its support to Israel," said a 24-year-old Palestinian gunman named Mustafa.

Another demonstrator said: "We are so happy that America was hit. America is against us in supporting Israel".
