In a series of tweets just past 1:15 am on Saturday, President Mohamed Morsy offered his condolences to the families of those killed in Friday's' clashes.
This as protesters continued deadly face-offs with security forces in governorates around the country, which have so far led to at least nine deaths, eight in Suez and one in Ismailia.
More than 450 have been injured in the violent clashes, which escalated late Friday evening after earlier peaceful protests commemorating the anniversary of the 25 January uprising.
Morsy, the presidency and the government have been silent for hours as clashes intensified well into the night.
Mass protests had erupted after Friday prayers against the Brotherhood's monopolization of power and demanding retribution for the revolution martyrs, in cities across the country.
In his tweets, Morsy sent condolences to "all Egyptians and to the families of Suez," to the martyrs from both security and civilians, who lost their lives in the "atrocious violence."
He vowed that the state bodies will not hesitate to go after the criminals and bring them to justice, adding that the state will exert its maximum effort to protect peaceful protests.
"I call on all citizens to hold on to the noble principles of the Egyptian revolution in expressing opinions freely and peacefully," he wrote on twitter.
In response, reform leader and Dostour Party head Mohamed ElBaradei, tweeted: "What we have seen so far from the president and his government in dealing with this tragedy we are living is the utter lack of responsibility."
