A man named only as Ashfaq has been charged with his murder, according to local police official.

Mushtaq allegedly kicked Ashfaq out of the WhatsApp group following an argument, according to a statement by Mushtaq’s brother.

He said that both parties had arranged to meet and reconcile but alleges that Ashfaq turned up with a gun and opened fire, killing his brother.

Ashfaq was angry “in reaction to removal from WhatsApp group,” according to his statement.

Mushtaq Ahmed was shot dead on Thursday evening in Peshawar, the capital of Khyber Pakhtunkhwa, a province that borders Afghanistan, which has a history of bloody sectarian violence.

The availability of firearms, the influence of tribal customs, and sometimes weak law enforcement contribute to the frequency of such incidents.
