An Egyptian court has sentenced 37 people to jail for joining or supporting the Islamic State (IS) group in the Sinai peninsula.

The area has seen a militant insurgency which has led to the deaths of hundreds of security personnel.

The jailed men were accused of planning attacks and spreading IS ideology.

Eight of the defendants were handed life sentences.

Mass sentencing under President Abdul Fattah al-Sisi has drawn criticism from human rights group who have called for fairer trials.
