called on Egypt's government and opposition on Saturday to engage each other in constructive dialogue and prevent violence spilling out across the region.
Bloodshed on Friday killed three people, including an American student, and mass rallies are planned for Sunday aimed at unseating Islamist President Mohamed Morsi.
Obama said he was "looking at the situation with concern".
Hundreds have been maimed and at least eight killed in street fighting for over a week as political deadlock deepens. On Friday, a bomb killed a protester at a rally by the Suez Canal. Washington is pulling non-essential staff out of Egypt.
"Every party has to denounce violence," Obama said at the other end of Africa, in Pretoria. "We'd like to see the opposition and President Morsi engage in a more constructive conversation about how they move their country forward because nobody is benefiting from the current stalemate."
He added that it was "challenging, given there is not a tradition of democracy in Egypt".
