Residents said relatives of Ms Bibi had told the couple they supported the marriage and invited them to the town, where they were drugged.

Muhammad Ijaz, who runs a mobile phone shop, said: "Their legs and arms were tied while their mouths were gagged with pieces of cloth. The father of the girl announced loudly that he was going to slit the throat of her daughter and her husband."
A crowd gathered as they were brought to the courtyard of the family house. Someone said the children should be sent away, but Ms Bibi's father told them to stay and watch, Mr Ijaz said.
"He said they should learn what would happen to them if they married someone of their own choice," he explained. Honour killings are nothing new in Pakistan. Hundreds go unnoticed every year, written off as domestic accidents or suicides. Human rights groups say almost 900 were reported in 2013, but the real number may be much higher.
The practice came to global attention last month when a pregnant woman was bludgeoned to death by her relatives in a busy Lahore street.
Watch: Pakistan woman stoned to death over honour
Farzana Parveen was murdered close to the city's court complex which was teeming with police officers. She died amid a dispute between her husband and her parents over the bride price paid for her hand. Nawaz Sharif, the prime minister, demanded that police chiefs explain why officers failed to intervene. The case also prompted moderate clerics to issue a fatwa condemning honour killings.
It seems to have made little difference.
The weekend's newspapers continued their roll call of shame. In one story, a young couple were shot dead by the wife's father for apparently marrying without permission.
