For the violent mob execution of a Sri Lankan factory manager accused of blasphemy, a Pakistani court sentenced six men to death and scores more to prison terms ranging from two years to life.

Last December 3, a vigilante attack in Sialkot sparked uproar, prompting then-Prime Minister Imran Khan to call it a “day of shame for Pakistan.”

Few issues are as galvanizing in Pakistan as blasphemy, and even the slightest suggestion of an insult to Islam can supercharge protests and incite lynching.

On Monday, prosecutors said 88 of 89 people on trial for the murder of Priyantha Diyawadana had been convicted, with six sentenced to death, nine to life in prison and the rest jail terms ranging from two to five years.

“The prosecution team worked very hard to present its case to the court and to reach this judgment,” Abdul Rauf Wattoo, the lead public prosecutor, told AFP.

“We are satisfied with the outcome.”

The trial was overseen by a special anti-terror court, established to speed up justice in high profile cases that can otherwise spend years being processed.

At the time of the killing, local police officials told AFP that rumors spread that Diyawadana had torn down a religious poster and thrown it in the dustbin.

Several gruesome video clips shared on social media showed a mob beating the prone victim while chanting slogans against blasphemy.

Other clips showed Diyawadana’s body set ablaze.

Many in the mob made no attempt to hide their identity and some took selfies in front of the burning corpse.

Rights groups say accusations of blasphemy can often be wielded to settle personal vendettas, with minorities largely the target.

In April 2017 an angry mob lynched university student Mashal Khan when he was accused of posting blasphemous content online.

After being wrongly accused of desecrating the Koran, a Christian couple was killed and their bodies burned in a kiln in Punjab in 2014.
