West Bank workers have blocked access to Yasser Arafat's grave site before the exhumation of his body this month.
The location of the Palestinian leader's remains has been circled with tarpaulin and roads leading to the mausoleum have been closed.
Officials, who spoke on condition of anonymity, said the Palestinian Authority had insisted on privacy and did not want the exhumation of its former leader to be observed by the media and others.
