The Egyptian Health Ministry says the death toll from violence following a crackdown on two camps housing supporters of the ousted president has risen to 638.
Ministry spokesman Mohammed Fathallah told The Associated Press on Thursday that the number of injured in the previous day's violence also has risen to 3994.
In Cairo, at the Al-Iman mosque, dozens of corpses of protesters clad in white shrouds were lined up before grieving relatives.
Wednesday's violence began when police moved to clear two protest camps housing mainly Islamist protesters calling for Mohammed Morsi's reinstatement. The crackdown prompted clashes elsewhere in Cairo and other cities.

Fathallah said 288 of the dead were killed in the larger of the two camps, in Cairo's eastern Nasr City district.
