The opposition National Salvation Front will hold a meeting on Monday at 1pm in the headquarters of the liberal Wafd Party in Cairo to decide on President Mohamed Morsi's invitation for a national dialogue.

The president on Sunday night invited eleven parties to a national dialogue, including the Socialist Popular Alliance, liberal Constitution Party, head of the Popular Current Hamdeen Sabbahi, moderate Islamist Wasat Party, Salafist Nour Party, and the Muslim Brotherhood's Freedom and Justice Party.

The Socialist Popular Alliance Party has already rejected the president Mohamed call for a national dialogue, and demanded the dismissal and the trial of the interior minister for "killing protesters."

Tens of protesters have been killed in Port Said, Ismailia and Suez in clashes with the police in the past 72 hours in anti-Morsi demonstrations on the second anniversary of the 25 January revolution.
