Palestinians have been marking the 64th anniversary of the event they call the “Nakba” or “catastrophe”, the day when hundreds of thousands were forced from their villages as the state of Israel was created.
Many combined it with celebrations for the end of a hunger strike by Palestinian prisoners in Israeli jails.
There were some clashes between Palestinians and Israeli troops, in Bethlehem and at two checkpoints near Jerusalem.
In East Jerusalem, protesters burned Israeli flags. Stones were thrown at Israeli troops, who responded with tear gas and rubber bullets.
The trouble overshadowed the end of the hunger strike which is an emotional issue for many Palestinians.
Today’s descendants of the Palestinians who left their homes in 1948 number several million, many still living in refugee camps.
Many still vow to return to the villages their families lost.
Palestinian President Mahmoud Abbas said the day unites all Palestinians.
In Gaza Hamas’ leader said they would not accept any proposal that abandons the right of return.
