Israel has sent security reinforcements to the town of Shfaram, where an Israeli soldier was lynched by an angry crowd after he shot dead four Israeli Arabs on a bus.
The 2,000 extra officers will try to prevent tension escalating in the wake of the incident, as Israeli Arabs stage a general strike over the killings.
The 19-year-old gunman had deserted from the Israeli Army in protest against the evacuation of settlements in the Gaza Strip.
The Israeli Prime Minister, Ariel Sharon, called the gunman a 'bloodthirsty terrorist'.
