CAIRO (AP) - Hundreds of Egyptian protesters rallied in Cairo demanding the ouster of the nation's embattled prosecutor general after a court ruled that his appointment by President Mohammed Mursi was illegal.

The protesters, clapping and beating drums, sealed off the office of Prosecutor General Talaat Abdullah with locks and chains and displayed a sign that read: "Leave. Enough."

The protesters also were upset about arrest warrants Mr Abdullah issued this week against five of Egypt's most prominent pro-democracy activists, alleging that they used social media to instigate fierce clashes a week earlier near the headquarters of Mursi's group, the Muslim Brotherhood.

Mr Abdullah issued the warrants a day after the president delivered an angry speech vowing to take action against opposition.
