Nine Palestinians have been killed during clashes with Israeli forces on the Gaza border with Israel.
The Gaza health ministry said at least 200 people were wounded during today’s protests.
Palestinian protesters set fire to pre-prepared mounds of tyres as confrontations with Israeli troops continued for a second week.
Thousands have gathered at encampments at various locations along the 65km border as part of a six-week-long demonstration with the protesters demanding a right of return for refugees and their descendants to areas now in Israel.
Israel has long ruled out any right of return, fearing it would lose its Jewish majority.

Twenty Palestinians have died since the demonstrations near the heavily guarded border fence began on 30 March.
Seventeen of the 20 Palestinian dead were killed by Israeli gunfire on the first day of protests a week ago, medics said.
The deaths drew international criticism of Israel's response, which human rights groups said involved live fire against demonstrators posing no immediate threat to life.
The United Nations human rights office urged Israel to exercise restraint.
Israel said it is doing what it must to defend its border and that its troops have been responding with riot dispersal means and fire "in accordance with the rules of engagement".
An Israeli military spokesman said that the army "will not allow any breach of the security infrastructure and fence, which protects Israeli civilians".
Hamas spokesman Hazem Qassem urged protesters to keep rallies peaceful. "Maintaining the peaceful nature of the protests will strike all fragile Zionist propaganda," he said.
The United States has criticised protest organisers. "We condemn leaders and protesters who call for violence or who send protesters - including children - to the fence, knowing that they may be injured or killed," US President Donald Trump's Middle East peace envoy, Jason Greenblatt, said yesterday.
The protest action is set to wind up on 15 May, when Palestinians mark the "Naqba", or "Catastrophe", when hundreds of thousands fled or were driven out of their homes during violence that culminated in war in May 1948 between the newly created state of Israel and its Arab neighbours.
