CAIRO (AP) — More than 50 people are dead after security forces and Islamist protesters clashed across Egypt on Sunday.
Crowds from Egypt's two rival camps -- supporters of the ousted Islamist president, Mohammed Morsi, and backers of the military that deposed him -- poured into the streets and turned on each other.
Several neighborhoods of the capital, Cairo, resembled combat zones after street battles that raged for hours.
Sunday's death toll was the highest on a single day since Aug. 14 when security forces raided two sit-in protest camps by Morsi supporters, killing hundreds.
Even as fighting continued in the streets, the military went ahead with lavish celebrations for the national holiday marking the 40th anniversary of the start of the 1973 Mideast war with Israel.
In the evening, a concert was aired live on state TV from a military-run Cairo stadium where pop stars from Egypt, Lebanon and the Gulf sang anthems to the army and dancers twirled on stage before a cheering crowd.
