Palestinians in Hebron, the Nablus area and Bilin clashed with Israeli troops on Friday (March 1).

In Salfit, on the outskirts of Nablus, a group of Palestinians prayed at a West bank hilltop near the Jewish settlement of Ariel. The group clashed with Israeli troops at the scene, throwing stones at the soldiers who responded with volleys of tear gas.

At the entrance to Nablus at Howara checkpoint black smoke was billowing from tyres set ablaze. Soldiers could be seen massing up at the checkpoint. Howara has been a flashpoint for violence for the past three weeks on Fridays.

In Hebron, for the second week in a row, protesters threw stones at soldiers who fired tear gas, stun grenades and rubber coated bullets.

Reuters' video shows one Palestinian youth, who appears to be unconscious, being carried by the army through the narrow streets of Hebron's old city. Witnesses said the boy had been shot with a rubber bullet to the head.

Hundreds of Palestinian demonstrators marched in the West Bank village of Bilin to mark eight years of regular protests against the controversial Israeli barrier erected to stop attacks on Israeli towns by Palestinian activists.

The Palestinian Prime Minister, Salam Fayyad attended the eight year anniversary march in Bilin, were he delivered a speech before marching with the protesters.

Fayyed was seen rubbing his eyes after tear gas was fired towards the marchers, and left the scene shortly afterwards.

Israel credits the barrier -- a network of fences interspersed with concrete walls, projected to be 720 km (450 miles) long when complete -- with stemming Palestinian suicide bombings that peaked in 2002 and 2003. But Palestinians condemn the project for looping around settlement blocs in the West Bank, where they want to set up a state.

With its weekly and often violent protests, Bilin has become a symbol of the Palestinian struggle.
