One of the leading candidates in Sunday’s Palestinian presidential election has been arrested by Israeli police on the last day of the campaign. Mustafa Barghouti was campaigning in East Jerusalem, an area that Palestinians hope to make the capital of a future state. The leading democracy campaigner was attempting to enter the al-Aqsa mosque for Friday prayers. Barghouti was detained by three plain-clothed Israeli policemen as he approached the mosque. Barghouti was bundled into a car and driven off. As we went on air there is still no word on where he was taken. He had been detained last week and prevented from campaigning in East Jerusalem when he was involved in a scuffle with Israeli soldiers at a West Bank checkpoint.
