More than 250 Palestinian prisoners are freed by Israel. Their release is being seen as a gesture of support for the Palestinian President Mahmoud Abbas. Not one of the released prisoners is from Hamas. Around 85 per cent of those freed are from Abbas' Fatah faction. The rest from smaller groups, like the Popular Front for the Liberation of Palestine. But the number is just a fraction of nearly 10,000 Palestinians still held in Israeli jails. Alan Fisher reports.
