A Pakistani court has sentenced Sawan Masih, a Christian man, to death after finding him guilty of blasphemy. Masih's case gained prominence last year when accusations of blasphemy sparked riots in his predominantly Christian neighbourhood, Joseph Colony. Mobs of 3,000 people burnt and ransacked more than 200 Christian homes in the eastern city of Lahore.
While the police arrested more than 83 suspects involved in the riots, there have been no convictions.
Pakistanis online were critical of the sentencing, calling on the international community to take action.
