Egypt's security forces have been accused of detaining dozens of children without charge and in some cases torturing and abusing them, prompting a condemnation from the United Nations.

Scores of children were detained across the country during protests marking the anniversary of the country's revolution.

The government says there are laws in place to protect minors, but that they are not always enforced.

Al Jazeera's Sherine Tadros reports from the Egyptian city of Alexandria, where she spoke to one boy who described his harrowing experience.
