One man is dead and 17 injured after a truck collided with vehicles and pedestrians in Tel Aviv on Sunday.
Police say the driver was an Arab Israeli who’s now under arrest, but they can’t yet be certain if it was an accident or a deliberate attack.
All weekend Palestinians have been demonstrating to mark Nakba, or catastrophe day, during which they mourn the creation of Israel in 1948, and the subsequent exodus of refugees.
Some of those protests have descended into clashes with police.
In Jerusalem the security forces are on high alert, after the death of a Palestinian teenager during rioting on Saturday. Identity cards are being carefully checked of anyone coming into the area.
In Gaza Palestinians held morning prayers to mark Nakba. Later the Hamas leader Ismail Haniyeh told worshippers that what he called the Zionist programme is being defeated.
In Ramallah the mood seemed somewhat more celebratory with hundreds of Palestinians taking to the streets waving their national flag, even if technically at least, they don’t yet have an internationally recognised homeland.
