Thousands of Americans joined rallies Sunday to support one side or the other in the widening Middle East conflict.

Up to 10,000 people gathered in Los Angeles for a pro-Israel demonstration addressed by the governor of California, former action-film star Arnold Schwarzenegger.

The crowd cheered as Schwarzenegger stressed his support for Israel, saying, "Every nation has the right to defend itself against terrorist attacks."

The mayor of Los Angeles, Antonio Villaraigosa, delivered a similar message when he addressed the rally, sponsored by the Jewish Federation of Greater Los Angeles.

The local Muslim group protested what it called Schwarzenegger's one-sided view of the Middle East clashes.

Halfway across the country, in Dearborn, Michigan, more than 1,000 Lebanese-Americans took part in a mass protest Sunday to denounce Israel's military tactics. They prayed for the hundreds of people killed or wounded by Israeli air strikes and artillery barrages, and for tens of thousands of Lebanese forced to leave their homes.

The Dearborn area of southeastern Michigan is home to about 300,000 people of Arab descent.
