Israelis are glued to their TV sets and radios for news about the horror that has befallen the United States. Many Israelis have relatives in the U.S. cities of New York and Washington and are trying to reach their families for news of their welfare.

Israel has beefed up security around all U.S. installations in the country, and the consulate in East Jerusalem will be closed Wednesday to all street traffic. The Israeli government is offering to send Israeli rescue units to the United States.

Israeli President Moshe Katsav has expressed his shock over the terrorist attacks, which the official statement said was perpetrated by heartless and bloodthirsty individuals.

Prime Minister Ariel Sharon has canceled his appointments and called the U.S. ambassador to offer his condolences. Israel's Defense Minister has approved the dispatch of rescue units to help U.S. relief efforts. Israel evacuated its missions in the United States as a precautionary measure.

Palestinian leader Yasser Arafat has expressed his horror and condemnation. The leader of the radical Palestinian group, the Democratic Front for the Liberation of Palestine, has denied reports of DFLP links to the terrorist attacks.

But in some towns and refugee camps in the West Bank and Gaza Palestinian militants poured into the streets to celebrate. Anti-U.S. sentiment has increased among Palestinians who see Washington as too biased toward Israel in the peace process.
