LAHORE, Pakistan — An enraged mob tortured a Pakistani Christian couple and incinerated their bodies in a brick kiln in eastern Pakistan on Tuesday after they were accused of burning a Quran, police officials said.

The killings, which happened in the town of Kot Radha Kishan in Punjab Province, were the latest violent outbreak of religious intolerance in Pakistan, where members of minorities are frequently accused of blasphemy.

The two victims, Shahzad Masih and Shama Masih, who had four children and were believed to be in their mid-20s, both worked as laborers at a local brick kiln. The accusations against them began after burned pages of the Quran were said to have been found in their trash.

On Tuesday, as word spread, the couple were locked up in a room adjacent to the brick kiln by their employer, Yousaf Gujjar, who also had a running dispute with the couple over money. Some accounts in local news media suggested that Mr. Gujjar accused them of blasphemy after they refused to repay money he had lent them.
