Jewish extremist groups prepare to march through Jerusalem

Jewish extremist groups prayed and prepared to march through Jerusalem Thursday in a move expected to stoke tensions following a deadly Palestinian car attack and clashes at the flashpoint Al-Aqsa mosque compound.

Israeli police set up concrete barriers and roadblocks in annexed Arab east Jerusalem, a day after a Palestinian deliberately ran over two groups of pedestrians, killing a policeman, in the second such attack in a fortnight.
