Fourteen Islamist women jailed for 11 years each for demonstrating in Egypt will be released after a court slashed their sentences to one-year suspended terms in a case that outraged opposition groups and human rights campaigners.

Seven girls aged under 18 had also been sent to juvenile prison in the same case last month, for obstructing traffic and damaging property during a pro-Islamist protest in October.

A juvenile court put the teenagers on probation for three months. Once the paperwork is completed, they will all be released.
