CAIRO, Oct 7 (Reuters) - The death toll from clashes in Egypt rose to 53 on Monday as calm returned to the streets after one of the bloodiest days since the military toppled Islamist President Mohamed Mursi in July.
Traffic flowed normally in central Cairo where thousands of Mursi supporters had battled security forces and army supporters on Sunday on the anniversary of the 1973 war with Israel.
State radio said security forces had regained full control of Egypt, which signed a peace treaty with Israel in 1979. In addition to the dead, the Health Ministry said 271 people had been wounded in the clashes. Most of the casualties were Mursi supporters, security sources said.
Further confrontations may shake Egypt this week. An alliance that includes Mursi's Muslim Brotherhood has urged Egyptians to stage more protests against the army takeover from Tuesday and gather on Cairo's Tahrir Square on Friday.
Political tensions since the army unseated Mursi on July 3 have unnerved foreign investors and hammered tourism, a pillar of the economy, but there is no sign of reconciliation between the Brotherhood and the army-backed government.
Security forces smashed pro-Mursi protest camps in Cairo on Aug. 14, killing hundreds of people. In an ensuing crackdown, many Muslim Brotherhood leaders were arrested in an attempt to decapitate Egypt's oldest Islamist movement.
Authorities had warned that anyone protesting against the army during Sunday's 1973 war anniversary would be regarded as an agent of foreign powers, not an activist - a hardening of language that suggests authorities may crack down harder.
The Brotherhood remains defiant, organising demonstrations, even if they are much smaller than ones staged weeks ago.
Army chief General Abdel Fattah al-Sisi, in an interview published on Monday in a privately owned Egyptian newspaper, al-Masry al-Youm, said Egypt's national interests differed from those of the Brotherhood as an organisation.
Sisi, in the interview conducted before Sunday's violence, also spoke about his previous meetings with Mursi, whose time in office he said had driven Egypt in the direction of civil war.
"I told Mursi in February you failed and your project is finished," al-Masry al-Youm quoted Sisi as saying.
Sisi denied Brotherhood allegations that the army had intended to remove Mursi through a coup, saying it had only responded to the will of the people.
Before Mursi's overthrow, Egyptians disillusioned with his year-long rule had held huge rallies demanding that he quit.
Last month, a court banned the Brotherhood and froze its assets, pushing the group, which had dominated elections held in Egypt after Hosni Mubarak's fall in 2011, further into the cold. (Additional reporting by Yasmine Saleh; Editing by Michael Georgy and Alistair Lyon)
