Palestinian Land Day rallies were marked Friday by clashes with Israeli security forces which fired rubber bullets, tear gas and stun grenades to break up crowds.
Some Palestinians threw stones at Israeli forces at several checkpoints between Israel and the Palestinian territories.
Palestinians had called for a "Global March to Jerusalem" to mark a day of protest against Israeli policies that they say have taken away their land.
Israeli forces are on high alert at border crossings with Lebanon and Syria. But there were no reports of fences being breached as they were during demonstrations on Land Day last year.
Some information for this report was provided by AP, AFP and Reuters.
