Israel clash over anti-Arab march

Israeli police have clashed with protesters in the Arab town of Umm al-Fahm in northern Israel, as Israeli far-right activists held a rally there.

The security forces fired tear gas and arrested some Arab protestors.

The Jewish marchers are followers of a far-right movement which believes Arabs should be expelled from Israel and the West Bank.

The BBC's Rupert Wingfield Hayes described the scene at the height of the trouble.
