President Mohamed Morsi is currently in the Hadayek El-Qobba presidential palace, a source who requested anonymity told Ahram Arabic Website on Sunday.
According to the source, Morsi is keeping a close eye on the unfolding demonstrations nationwide. In meetings with the interior and defense ministers, Morsi has stressed the need to prevent clashes between Egyptian citizens, the source added.
The source also said that the presidential guards, who are responsible for protecting the president, are the ones who decide where the president operates.
The president's office recently announced that it has moved its daily work to El-Qobba palace.
Thousands will march from a number of locations towards the Ittihadiya presidential palace on Sunday to call for Morsi's resignation and early presidential elections.
According to the opposition, Morsi's first year in office failed to fulfill the demands of the January 25 Revolution.
Morsi stated in a speech on Wednesday that early presidential elections are unconstitutional and an obstacle to true democracy.
