Israel's Prime Minister Benjamin Netanyahu has condemned the overnight attack on his country's embassy in the Egyptian capital.

An aide to the prime minister says Netanyahu on Saturday denounced the attack as a "serious incident" and a "blatant violation of international norms."

He says Netanyahu thanked Egyptian authorities for helping rescue six Israeli employees trapped inside the embassy during the attack but said the incident itself was a "severe injury to the fabric of peace with Israel."

The aide, who said he heard Netanyahu's remarks, spoke on condition of anonymity because he wasn't authorized to speak to the press.

CAIRO (AP) _ A senior Egyptian official says at least three people died and more than 1,000 were hurt during street clashes with police and army troops after an angry mob attacked the Israeli embassy in Cairo.

Deputy Health Minister Hamid Abaza say one of the three fatalities in the violence late Friday was a man who died of a heart attack.

Abaza told The Associated Press on Saturday he doesn't know the cause of the other two deaths. He says at least 1,093 people were injured in the clashes.

The protesters pelted the police and the military with rocks, prompting the troops to fire tear gas and shoot into the air. Only 38 of the injured remained in hospital.

Earlier, the protesters tore down a security wall outside the Israeli mission and stormed the embassy's offices.
