A mob in Pakistan has killed a mother and two of her grandchildren.
The victims were members of the Ahmadi minority community in the town of Gujranwala, 220 km, southeast of Islamabad.
The violence began with an argument about a Facebook posting made by an Ahmadi youth.
The alleged ‘blasphemous’ material caused a crowd of 150 to gather at a police station calling for action against the teenager.
Another mob then attacked and set fire to Ahmadi houses.
Under a 1984 law Pakistan classes Ahmadis as non-Muslims and many consider them heretics.
Ahmadis see themselves as Muslims, but with a different belief system.
Accusations of blasphemy are rocketing in Pakistan from one in 2011 to 100 so far this year.
It is the worst assault against the Ahmadi community since attacks on their places of worship left 86 Ahmadis dead four years ago.
