Activists in Syria have called for a second day of mass demonstrations to protest the alleged torture and killing of a 13-year-old boy.

Hamza Al Khatib's mutilated body was returned to his family this week, a month after he went missing while participating in a demonstration.

Foreign media are banned from reporting inside Syria.

Al Jazeera's Sophie Jackson reports on some of the latest videos that have emerged.
