Egypt death sentences: Gunshots and tear gas at Port Said jail
An Egyptian court has sentenced to death 21 defendants over clashes between rival football fans in which 74 people were killed in February 2012.
The riots - Egypt's worst-ever football disaster - began after a top-league game at Port Said stadium.
The ruling sparked clashes outside Port Said prison, where the defendants are being held.
Families of the people who received death sentences were seen weeping and running away from tear gas and gunshots.
