An Egyptian court has charged 215 supporters of the proscribed Muslim Brotherhood with establishing a militant group and killing six policemen.
Chief Prosecutor Hesham Barakat said the Helwan Brigade was formed to support the banned organisation and accused them of killing the policemen in Cairo.
The government arrested thousands of those thought to be supportive of the Muslim Brotherhood since President Abdel Fattah al-Sisi came into power in 2013, after the ouster of the brotherhood's Mohammad Morsi.
Earlier this month 183 members of the group were sentenced to death.
