JERUSALEM (AFP) - Israel's law and order chief said some Muslims would be denied entry to Jerusalem's Al-Aqsa mosque compound on Friday when Palestinians begin mourning the creation of the Jewish state. Public Security Minister Yitzhak Aharonovitch told public radio Thursday that police would "thin out the number of worshippers at the Temple Mount" -- the Hebrew term for the compound inside the walled Old City which houses the Al-Aqsa mosque and the Dome of the Rock. Israeli police spokesman Micky Rosenfeld confirmed that some restrictions would be in force during the Friday prayers but he was not immediately able to give details. A police statement said that officers, reinforced by paramilitary border police, "will deploy from early tomorrow morning in east Jerusalem and in the alleys of the Old City in order to preserve the law and security." It said that security forces manning crossing points into annexed east Jerusalem from the rest of the West Bank would be beefed up and there would be increased checks on vehicles entering the city. An army spokeswoman said that the military was ready for any scenario. The move to limit access to what is the third holiest site in Islam after Mecca and Medina, came as the Palestinians were poised to begin a series of marches and demonstrations in the run up to Nakba Day, which will be commemorated on Sunday. Activists behind a website called "The Third Intifada" have also called for a new uprising, which would see thousands of Palestinian refugees march towards homes which they fled from or were forced out of when Israel was created in 1948. A senior Palestinian official said on Thursday he hopes a Palestinian unity government will be formed within a week under an April 27 reconciliation accord. "I hope that within a week we will have a new government installed by consensus," Nabil Shaath, a senior figure in the Fatah party of Palestinian president Mahmud Abbas, told reporters in the West Bank city of Ramallah. He said delegations from rival factions Fatah and Hamas would meet within days in the Egyptian capital to draw up the government list. Meanwhile, Israeli military admitted on Thursday that army was using attack dogs to stop Palestinians trying to damage the West Bank separation barrier in order to illegally enter Israel through the gaps. An army statement said that in the past few years, a stretch of the barrier in the southern West Bank had been purposely damaged to permit the passage of terrorists into Israel in a move which endangers Israeli lives. In order to prevent damage to the security fence, the IDF (army) uses a number of different measures, including the canine unit and its trained dogs, while taking appropriate precautionary measures to avoid unnecessary injury, it said. The use of dogs actually limits bodily injuries and obviates the use of other measures, the statement said.
