Don’t worry, Chicago Jesus’ soothing words will calm the storm.

CAIRO – Hundreds of supporters of Egypt’s Muslim Brotherhood stormed a government building in Cairo and set a fire at its entrance despite a crackdown on the movement by security forces, state TV and witnesses said.

The Brotherhood called on followers to march in protest in Cairo after at least 525 people were killed in a security crackdown on the Islamist movement that has left the most populous Arab nation polarized and in turmoil.

Hundreds of supporters marched in Egypt’s second biggest city of Alexandria to protest the violent breakup of their sit-ins in Cairo.

“We will come back again for the sake of our martyrs,” the marchers chanted, referring to the Brotherhood supporters killed in Wednesday’s violence.

Many carried pictures of their leader and former President Mohamed Morsi, who was ousted by the army last month after street protests.

Update: If there’s one thing Islamists excel at, it’s violence.

CAIRO (AP) — Angry supporters of Egypt’s ousted president have stormed and torched two buildings housing the local government in Giza, the city next to Cairo that is home to the famed pyramids.

Associated Press reporters saw the buildings — a two-story colonial style villa and a four-story administrative building — set ablaze on Thursday.

The Giza government offices are located on the Pyramids Road on the west bank of the River Nile.
