Israeli troops fired tear gas and live bullets at Palestinians taking part in weekly protests at the Gaza Strip border with Israel on Friday, injuring at least 100 people, medics said.

The army said it was taking action to disperse thousands of Palestinians, some of whom threw rocks the troops and burned tyres, and prevent any breach of the fortified frontier fence.

Israeli forces have killed at last 120 Palestinians in protests along the border since a campaign was launched on March 30 to demand the right to return to ancestral lands that are now part of Israel, hospital officials say. Israel says the dead included Hamas and other militants who used civilians as cover for infiltration attempts.
