Son of Top Muslim Brotherhood Leader Killed

Egypt's Muslim Brotherhood says a son of its spiritual leader was killed during fierce clashes in downtown Cairo, as hundreds of Islamists supporters of the country's ousted president remained barricaded inside a mosque. The group's political arm said on its official website today that Mohammed Badie's son Ammar was killed yesterday. That's when the Muslim Brotherhood took to the streets in a "Day of Rage," ignited by anger at security forces over clearing two sit-in camps earlier in the week.

The death toll in yesterday's clashes rose today to 173 people killed nationwide, said a government spokesman. Another 1,330 people were wounded. Meanwhile, hundreds remained inside the al-Fatah mosque in Cairo this morning after barricading themselves inside overnight. A Muslim cleric said there were ongoing negotiations with the military to have protesters safely leave. But many tell the BBC they don't trust security forces, who are massed outside in riot gear.
