Washington: Egypt's first democratically elected President Mohammed Morsi reportedly left the presidential palace in the wake of violence that erupted between police and at least 100,000 protesters gathered in Cairo.
In a brief outburst, police fired tear gas to stop protesters approaching the palace in the capital's Heliopolis district.
Morsi was in the palace conducting business as usual while the protesters gathered outside.
But he left for home through a back door when the crowds 'grew bigger,' Fox News quoted a presidential official, as saying.
According to the report, the official said Morsi left on the advice of security officials at the palace and to head off "possible dangers" and to calm protesters.
Morsi's spokesman, however, said the president left the palace at the end of his work schedule through the door he routinely uses.
According to the state-run media, the brief outburst of violence left 18 people injured, none seriously.
Protesters gathered as tensions grew over Morsi's seizure of nearly unrestricted powers and a draft constitution hurriedly adopted by his allies, the report said.
