Egypt's President Mohammed Morsi has said he will respect free speech, but will not tolerate killings or sabotage.
"We respect peaceful freedom of speech but will never allow anyone to take part in killings and sabotage,"he said in the speech on Thursday.
His remarks came as clashes in Cairo continue to grow over a controversial draft constitution, the Sydney Morning Herald reports.
Opposition activists say the draft constitution fails to protect freedoms and minority rights.
They accuse Morsi and the Brotherhood of betraying the aims of last year's uprising against the former president Hosni Mubarak.
According to the paper, Morsi, who won an election in June, and his Islamist supporters say they are trying to protect the gains of the revolution against remnants of the old regime. (ANI)
