Egypt has released from custody 163 more members of the Muslim Brotherhood.

More than 700 members of the banned opposition group were arrested during protests last month. Despite Sunday release, the movement's main leaders and hundreds more are still behind bars.

In May, the Muslim Brotherhood staged a series of protests over an amendment to Egypt's constitution. The amendment, which has since been approved, allows more than one candidate to run in presidential elections. The Brotherhood protested the measure because it also included tough conditions for independent candidates, effectively excluding those not approved by the ruling party.

Opposition leaders said the amendment ensures there will be no serious challenges to President Hosni Mubarak.
