There have been almost daily clashes in east Jerusalem between Palestinian protesters and Israeli police in recent months, with much of the unrest focused on the city's sacred compound revered by both Jews and Muslims.
It is the holiest site for Jews, who call it the Temple Mount because of the revered Jewish temples that stood there in biblical times; Muslims refer to it as the Noble Sanctuary and it is their third holiest site, after Mecca and Medina in Saudi Arabia.
"Alongside our determined stance for our rights, we are determined to maintain the status quo for all the religions in order to prevent an eruption."
Israel captured east Jerusalem with its sites sacred to Jews, Muslims and Christians - from Jordan in the 1967 war.
