The Arab Street is raging.

CAIRO, Egypt - Several thousand protesters at one of Cairo’s main mosques called Friday for holy war against Israel to help the Palestinians in their conflict with the Jewish state.

More than 3,000 people packed Al-Azhar Mosque, the most prominent institution in the Sunni Arab world, for prayers and a demonstration organized by the Egyptian government’s top rival, the Muslim Brotherhood.

“Rulers of Arab countries, start holy war! God is great!” men shouted, their voices ringing through the rafters of the 1,000-year-old building.

And so is the Turkish Street.

ISTANBUL, Turkey - Thousands of angry Turks burned an Israeli flag Friday and chanted “Murderer Israel, Get out of Palestine!” to protest Israel’s offensive into the Gaza Strip.

Hundreds of women, wearing black chadors or covering their heads with Islamic-style head scarves, carried Palestinian flags and banners which read: “Israel is burning Palestine.”

Police said about 5,000 people participated in the protest outside Istanbul’s Bayazid Mosque.
