Ramallah (Palestine) - Worshippers would not return to a contested shrine until Israel removes the new railings and cameras it installed after a deadly attack there, a senior Muslim official said on Wednesday. Ikrema Sabri, the head of the Supreme Islamic Committee, said that even after Israel removed metal detectors at the site more steps were required. He said mass prayer protests would continue until the gates of the compound were opened, metal railings and an iron bridge removed and newly installed cameras taken down. He said a lawyer working on behalf of the Muslim administration of the holy site will be in touch with Israeli police to make the demands. "We will not enter the mosque until these things are implemented," he told The Associated Press. "Now we are awaiting the response of the police." The demand sets off the prospect of a renewed showdown ahead of Friday prayers at the site, when a large number of worshippers arrive for the centerpiece of the Muslim prayer week, and extends a crisis Israel was eager to resolve. Israel installed the new security measures earlier this month after Arab gunmen shot and killed two police officers from within the site. Under intense pressure, it removed the metal detectors and said it planned to install sophisticated security cameras instead. In response to that attack, Israel closed the shrine for two days for weapons searches and installed the metal detectors. The decision quickly triggered Muslim protests amid rumors that Israel was trying to expand its control at the site under the guise of security, a claim Israel strongly denied.
