Palestinians protested Wednesday for the annual commemoration of what they call the Nakba, or catastrophe, when hundreds of thousands were expelled or fled during the 1948 war surrounding the creation of Israel.
Thousands gathered at various locations along the volatile border fence between Israel and the Gaza Strip, while crowds also demonstrated in the occupied West Bank.
Clashes erupted along parts of the border fence, with the health ministry in Hamas-run Gaza reporting 47 people wounded, but the protests were smaller and calmer than anticipated.
Palestinians in Gaza have regularly used kites with firebombs attached to them to set fires on the Israeli side of the fence.
Israel's military said around 10,000 "rioters and demonstrators" were along the Gaza fence.
"The rioters are setting tyres on fire and hurling rocks," it said in a statement.
