Pakistani police have arrested more than 40 suspects in connection with the killing of a Christian couple accused of desecrating the Koran.
Authorities say a Muslim mob beat Shehzad Masih and his wife, Shama, to death and burned their bodies on November 4 in the Punjab province town of Kot Radha Kishan, in the latest example of mob violence against minorities accused of blasphemy.
Prime Minister Nawaz Sharif called the murders "an unacceptable crime."
Punjab Chief Minister Shahbaz Sharif has formed a committee he says will fast-track the investigation and ordered police to beef up security in Christian neighborhoods.
Blasphemy is a hugely sensitive issue in the majority Muslim country, with even unproven allegations often prompting mob violence.
