CAIRO - Opponents of Egyptian President Mohamed Morsi will press ahead with a protest on Tuesday to demand the scrapping of a decree extending his powers, rejecting the Islamist's attempt to defuse a crisis that has brought violence back to Cairo's streets.

Morsi was accused of giving himself the powers of a modern-day pharaoh when he issued the decree last week that prevents legal challenges to any decision he takes until a new parliament is elected.

The president tried to ease tensions on Monday by agreeing to a compromise proposed by senior judges on the Supreme Judicial Council limiting the scope of presidential decisions that are immune from a court challenge.

But protesters camped out in Tahrir Square, the heart of the uprising that unseated Hosni Mubarak almost two years ago, said they would not leave until the decree was scrapped entirely.

Violence has flared in the past when supporters and opponents of Morsi held rival protests. However, the Muslim Brotherhood, the group that propelled Morsi to office in this year's presidential poll, cancelled their own demonstration in Cairo also planned for Tuesday.

One person has been killed and about 370 injured in violence since Morsi issued decree last Thursday.
