Black smoke from burning tires rose across the Gaza Strip. Dozens of children ran through the streets, many promising to carry out his legacy.
In the West Bank city of Ramallah (search), Palestinian flags at Arafat's battered compound were lowered to half staff. Television broadcast excerpts from the Quran (search) with a picture of Arafat in the background.
Israel closed the West Bank and Gaza Strip borders and sent troop reinforcements to the areas, while beefing up security at Jewish settlements amid concern over possible Palestinian rioting in the coming days.
"The Israeli Defense Forces are deploying to allow a dignified funeral ceremony for chairman Arafat," an army statement said.
